You use fractions when you cook, shop,etc.It is hard to avoid using fractions especially when you are doing the things above. I do not understand how people think you never will use what you learn in school.

Fractions are useful in two ways for many things: they delay division (4/5 is really 4 divided by 5) and they can compare parts to a whole (if there is 39573 out of 97334 things, then a little subtraction can tell you that there is another 57761 other things, and fractions come into play by allowing you to estimate what part of 97334 there is and isn't- about 57 out of 97 things or like 58% without having used a calculator is missing).

In these 2 ways, it has made general math easier when put in fractional form (7/16 * 2 is easier to multiply than .4375 * 2) so that people can do it in their heads. With the example just given, by first reaching 7/8 and using the somewhat common knowledge that 7 divided by 8 is .875, the computation was made easier because numerators and denominators can cancel out the way they do.
