Hello There!
We are going to be finding the sum of 5/7 and 2/7
STEP 1 We already have common denominators so now, it's just about adding what we already have.
STEP 2 Add 5 and 2 together and you will get a sum of 7 and your denominator will be left alone.
STEP 3 We will get a answer of 7/7 which is the same thing as 1.
