Please answer the question from the attachment.

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)
= $\frac{6}{8}$ = $\frac{3}{4}$
