Adding, Subtracting,Multipling, Dividing

Adding and Subtracting

Step 1- First you have to make sure you have a common denominator

Step 2- If you have a common denominator just add

Step 3- 3/5 + 4/5= ?

If you don't have a common denominator

You have to find a common denominator

So like for 2/2=4

3/2=6 = 1/6

Same with subtraction but remember to subtract not add. :)
