Step-by-step explanation:

Ignore the whole numbers(5 and 7), just for now

To find the difference, these fractions need to have the same denominator. You multiple them(make sure to multiple both the denominator and numerator) by numbers to get the denominators equal.

1/5 times 7/7 is 7/35

2/7 times 5/5 is 10/35

Now that the denominators the same, bring back the whole numbers and find the difference.

7 10/35 minus 5 7/35
