Answer:
12 [tex]\frac{7}{8}[/tex]
Step-by-step explanation:
First we need to find make the mixed fractions to improper fractions.
13 5/8 = 109/8
8 4/8 = 68/8
35= 280/8
Next is to find the LCD of the 3 terms
LCD is 8
We can therefore write this as
[tex]\frac{280}{8} -\frac{109}{8}-\frac{68}{8} = \frac{103}{8} or 12\frac{7}{8}[/tex]
