My report on Fractions

A while ago now Mr Rantana asked us to write a report on fractions and this is mine :

A fraction is a part of a whole (of anything).
There are two parts to a fraction: the denominator and the numerator. On the top of the vinculum (the line in the middle), there is the numerator and on the bottom there is the denominator. The denominator is always on the bottom and the numerator is on the top there is a trick to remember this, denominator D = down.

There are 3 types of fractions: normal ⅝, top-heavy16/4 and mixed 39/10. Now let’s talk about the different types of those types of fractions. Alright let’s start with the normal ones there easy just any 2 numbers but make sure the numerator is littler than the denominator, if you don’t that is what you would call a top-heavy fraction where the numerator is higher than the denominator to find out that you need to divide the denominator and the numerator and you will find the answer. And the last one mixed fraction, well all it is, is a whole number and a fraction e.g.: 2 and 2/3.
A fraction is a part of a whole; I’ll show you how they work. Let’s use 2/3, so there are 3 parts and you want 2 of them, or like a ½ of 22 (11) do you get it?
ADDING YOU CAN ADD THEM! Don’t think it’s hard, it’s really easy (only with common denominators though) e.g.: 2/3 + 1/3 =? What you do.
Well all you do is add the numerators together (2+1 =3) but make sure you don’t touch the denominator, unless they are different.
Ordering fractions, most people think that the bigger the fraction is the bigger it is that is false it’s the opposite e.g. 3/10 is smaller than 1/3.
Fractions are also related to percentages and decimals you can turn a fraction in to a percentage to a decimal and back to a fraction.

Finally remember that a fraction is the same as dividing so if you can divide you can work with fractions.
