Ms. SUE, Is this correct?

Question

4. 5/8 + 5/6 = 1 11/24

5. 13 1/2 + 7 2/3 = 21 1/6

Answer 1

5 / 8 = 3 5 / 3 8 = 15 / 24

5 / 6 = 4 5 / 4 6 = 20 / 24

5 / 8 + 5 / 6 = 15 / 24 + 20 / 24 = 35 / 24 =

( 24 + 11 ) / 24 = 1 + 11 / 24 = 1 11 / 24

Correct.

13 1 / 2 = 13 6 / 6 + 3 / 6 = 78 / 6 + 3 / 6 = 81 / 6

7 2 / 3 = 7 6 / 6 + 4 / 6 = 42 / 6 + 4 / 6 = 46 / 6

13 1 / 2 + 7 2 / 3 = 81 / 6 + 46 / 6 =

127 / 6 = ( 126 + 1 ) / 6 = 21 1 / 6

Correct.
