Addition of Fraction

Addition of fraction comes in two parts. Fraction with the same denominator and fraction with different denominator.

 Same denominator 

When adding fraction with the same denominator what is normally done is that we had the numerators and then put it over the common denominators.

For example    3/8 + 2/8. See that the denominators are the same we will add the 2 and the 3 which gives us 5 and the put it over 8, so our answer will be 5/8.

 Different denominators 

With different denominator the procedure for solving is different. What we must first do is to find the Least Common Multiple (LCM). the LCM is a number that both denominators can be divided into without leaving a remainder.

For example  3/5 + 1/4. firstly we must find a number that the two denominators can go in which in this case will be 20

12 +5    =    17

20
