Answer:

$\large\boxed{9-3(7)/(8)=5(1)/(8)}$

Explanation:

METHOD #1:

9-3(7)/(8)

Convert 9 the fraction with denominator of 8 and convert the mixed number to the improper fraction:

$(9\cdot8)/(8)-(3\cdot8+7)/(8)=(72)/(8)-(31)/(8)=(41)/(8)=(40+1)/(8)=(40)/(8)+(1)/(8)=5(1)/(8)$

METHOD #2:

9-3(7)/(8)=9-3-(7)/(8)=6-(7)/(8)=5+1-(7)/(8)=5+(8)/(8)-(7)/(8)=5(1)/(8)
