Answer:

9 7/8

Step-by-step explanation:

solution by separating parts:

1) rewrite equation with parts separated

= 6 +1/4 + 3 + 5/8

2) solve whole number parts

6 + 3 = 9

3) solve fraction parts

1/4 + 5/8 = ?

- find the LCD of 1/4 and 5/8 and rewrite to solve

LCD = 8

2/8 + 5/8 = 7/8

combining the whole and fraction parts:

9 + 7/8 = 9 7/8
