GMAS 6th Grade Mathematics Practice Test

What is the sum of 5/6 and 7/15?

8/5 1/3 13/10 39/60

Correct Answer:

13/10

Explanation:

Adding fractions requires a common denominator so you can combine the tops. Turn each fraction into an equivalent one with the same bottom, then add the tops and simplify. For 5/6 and 7/15, the common denominator is 30. Rewriting gives 5/6 = 25/30 and 7/15 = 14/30. Add them: 25/30 + 14/30 = 39/30. Simplify by dividing numerator and denominator by 3 to get 13/10, which is the final sum (1 and 3/10).
