Answer 1

Change it into improper fraction to make it easier or just solve it as is.
=$3\frac{5}{8}$-$2\frac{7}{8}$
=$\frac{29}{8}$-$\frac{23}{8}$
=$\frac{6}{8}$=$\frac{3}{4}$            
OR
=$3 \frac{5}{8}$-$2 \frac{7}{8}$
divide it to two parts:
3-2=1 and $\frac{5}{8}$-$\frac{7}{8}$=$\frac{-2}{8}$
$1\frac{-2}{8}$⇒(1×8-2=6)
=$\frac{6}{8}$=$\frac{3}{4}$
