Fraction

What is fraction ? Fraction is a part of a whole number. Imagine if a cake is considered a whole, when the cake is cut into 2 pieces , one of the pieces is considered 1 out of 2 , which is written as 1/2 . If we cut further to 4 pieces of cakes, each pieces will be 1 out of 4 , or written as 1/4 .

Now , when we perform an addition, 1/2 + 1/2 for example, the first thing to do is to make the number at the bottom equal (denominator) before summation.

For example 1/2 + 1/2 = 2/2 = 1

2/5 + 1/5 = 3/5

2/3 + 1/6 = 4/6 + 1/6 = 5/6 See here , we have turn 2/3 into 4/6 .

Is 2/3 = 4/6 ?
Let's explore this :

Imagine if a piece of cake being cut into 3 pieces and isolate the 2 pieces . If we cut the cake further into 6 pieces , the isolated 2 pieces will turn into 4 pieces . herefore 2/3 is equal to 4/6
