Question

How can you write 5/7 as the sum of fraction two different ways

Answer 1

Multiply the denominator by the whole number. Make that product the numerator. Let us now revisit the rule for changing a mixed number to an improper fraction 

Answer 2

One solution could be:

2/7 + 3/7 = 5/7

Another could be:

4/14 + 6/14 = 10/14 = 5/7
