Answer 1

5 11/45

Explanation:

13 4/9 - 8 1/5 = ?

First we need to find the common denominator between 9 and 5

The Least Common Denominator is 45

9 x 5 = 45

4 x 5 = 20

The first fraction simplified = 13 20/45

5 x 9 = 45

1 x 9 = 9

The second fraction simplified = 8 9/45

The answer is 5 11/45

Answer 2

5 11/45

121/9-->605/45

41/5-->369/45

now subtract

605/45-369/45=236/45 or 5 11/45
