  1. A day without decimals is really inconvenient, for example when i go to the canteen, when i am buying food. If the cost of the item, for e.g. a chicken stick. For free it would be too cheap. For $1 it would be too expensive, thus no one will buy it. With decimals, it is easier to set the right price for food so people are not inconvenienced.

  2. Without decimals, students will fret because everything seems to cost $1 or $2 or more. decimals ranges the costs of things

  4. A day without decimals is really inconvenient, for example when i go to the canteen and am buying food. If a fish ball is free, it would mean no buisness for the vendors. But if the vendors sold their fish balls for $1 each, it would not be affordable to students. Without decimals, it would be very difficult to set reasonable prices to students. Let's take the fish ball again for example, if we set the price $0.20 for one it would be much more reasonable. Notice that $0.20 is a decimal. Therefore, decimals are really important not only in Maths, but also in our everyday lives.

  5. A day without decimals is really inconvenient, for example if I buy something for $1.20 and you don't have the correct amount, I will have to pay with a $2 note. If there are no decimals, the stall aunties or uncles have to convert it into 200 cents and take that amount subtract 120 cents which will be equals to 80 cents and 80cents will be the change. Let's say, if we buy a piece of fishcake or maybe a fishball and it is free, the vendors will have no business and if it costs $1 or $2, the students would not be able to afford it. So, if the fishball or faiscake costs $0.20 and $0.40 respectively, the students would be able to afford it. Notice that $0.20 and $0.40 are decimals. Therefore, decimals are importantnot only in Math, but in our everyday lives.

  6. A day without decimals would be very inconvinient.If something is price at $0.40, they price would either be $0 or $1. 1 dollar is too expensive and zero dollars would mean free. And if they were to convert it all into cents, it would be very troublesome. If come thing is price at 3.20, the vendor will need to do 3x100 cents + 20 cents which will be 320 cents and that will be troublesome for them. And if we give them a $50 dollar note they will need to do 50x 100cents = 5000cents. And then they will need to do 5000-320=4680 for the change. And even if they have a calculator it will still take time.

  7. A day without decimals is really inconvinient especially when we want to buy something in the canteen. For example, when I want to buy something that has a decimal, like $0.50, without decimals, the price would be rounded of to either $1 or $0. Everything would have to be a whole number and things would be more expensive than they should be.(unfairly priced)

    Or to get the exact price, you would have to use a very troublesome and complicated mathod. I would have to convert the dollars to cents. e.g. $2.40=240 cents.

  8. Decimals make things more accurate and widen the range of numbers/prices...........

  9. A day without decimals is very troublesome and inconvinient. for example when you buy something that is supposed to cost 0.20 dollars, you would have to pay either 0 dollars or 1 dollar 0 dollars means its free and the stall owners wont earn any money, and 1 dollar is too expensive for children to afford. If u want to get the the exact amount, it would be really troublesome as you have to convert it all to cents. eg. $0.20 = 200 cents. this is rather easy but as the decimals get bigger, the stall owners will have problems calculating how much change to give you back. eg when something is like $2.20, they would do 2x100=200. 200+20=220. this is very troublesome. if you pay them $10,they would have to do 10x100 cents= 1000 cents. 1000 cents -220 cents=780 cents. this is very troublesome and time consuming. decimals also widens the range of numbers and prices, and is very very useful in not only math but also our daily lives:)

  10. A day without decimals is really inconvenient, for example when i go to the canteen, the food will cost one dollar and above if not it will be free.

  11. A day without decimals will be really inconvinient, for example when I go to the canteen, the food will cost 1 dollar or two dollars, or it will be free. With decimals, it can be from 10 cents to 9o cents, or 1 dollar and 10 cents.

  12. A day without decimals is really inconvenient, for example when I go to the canteen, the prices of food and drink will be either free, $1, $2 and so on. With decimals, the food may cost for example $1.20, so the canteen vendors earn more $$$$$. Also, If something costs for example $5.20, and you only have a $10 note, the canteen vendor may give you the change in $4.80, so you don't lose money.

  13. A day without decimals would be really bad. The price of foo and items would be rounded off. If you buy something cheap that cost 30 cents, and there were no decimals, we would have to round it off to either 0 cents, or 1 dollar. If you round it off to 0 cents, which is for free, the vendors will not earn anything at all. It would be just like giving free stuff when people are surposed to buy them. If you round it off to a dollar, the students would have a hard time buying food as all the food prices increases rapidly and many of them will not be able to buy food. But if there were decimals, it would be much easier and things would be cheaper. If a piece of fishball cost 50 cents for example, you give the vendors 1 dollar, they would just have to give you a change of 50 cents. It works both ways, for buyers, things are cheaper, for sellers, they can earn money. That's why decimals are so important, they not only are needed in math but also in your everyday life. When you eat, or drink, and watch a movie, you all have to spend money to buy things. If they are in a decimal form, then things would be much easier to purchase and it would make things much more convinient.

  14. A day without decimals is really inconvenient.I would be spending all of my poket money.All the prices of food and drinks will always be rounded up to the nearest dollar because there are no decimals.If the price is rounded down, the vendors will not be earning profit and they would never want to lose money hence all the prices will be rounded up to the nearest dollar.If there are decimals,the prices of the items will be much more reasonable than if there are no decimals.
    E.g If a bowl of noodles cost $1.50.If there are no decimals the price of the noodles will be $2 as $1.50 rounded up to the nearest dollar is $2.I there are decimals the item will just cost $1.50.
    Overall,i think that decimals are not just imporantant for mathematics but also for our daily lives such as for food,bills and salary.

  15. A day without decimals would be very inconvenient. For example if a plate of food costs $1.50, you could either pay $0, $1 or $2 (there are others except for the fact that nobody wants to pay more than necessary). $0 means free food and if it was free food the stall would have long closed down. $1 means there is a discount of 1/3 off and the vendor would not accept. $2 means paying extra money and the vendor would be more than happy to receive that.

  16. The stall keeper might shortchange me and I really hate to be shortchanged.

  17. But without decimals, prices would be more exact. Don't need to dig through my wallet for coins. More convenient for me.

  18. To me, a day without decimals is not at all inconvenient. So when I go to the canteen and buy food, the cost of the food will be in whole numbers ($1/$2/$3...) so we do not need to wait for the change and waste our precious and limited time during recess. Like that, we kids will not have many coins in our wallets putting more weight for us to carry. And since the food will be more expensive, the vendors will probably have to serve us with more food with better quality too. (For some of us)We also do not need to be asked to save money in our piggy banks, and even so if we ever save, we will save in whole numbers, which is much faster than saving cent by cent, and in that way, we will soon be rich!
    So think about it, a day without decimals could be even more convenient.

  19. Without decimals, exact amounts need to be rounded off to the nearest dollar. If the price is $0.60, and is rounded off to one dollar, then the shopkeeper gets profit. But if the thing is $0.40, then we would buy it for free. It may be good to us, but thinking about other people suffering, i kind of lose my appetite. These people are making a living, if everybody in the canteen chooses to buy that thing, the vendor would lose money.

  20. A day without decimels will really be a mess because we use decimal all the time just that we do not notice it e.g.if i go to a bookshop, and there is a thing that cost 10cents at first but because 10cents is 0.10 and is a decimal,the lowest pice will be $1 so we will make a loss of 90cents.

  21. A day without decimals would mean ranging everything from whole numbers onwards, which means that everybody would have to spend more of their pocket money on food.

  22. A day without decimals is really inconvenient, for example when I go to the canteen, when I look at the pricing, it would be very difficult. The canteen vendor cannot write $1.20, but has to write 120 cents. When the canteen vendor has to give us the change, they will have a very hard time calculating the change.
