see explanation below

(1) $\frac{1}{5}$ × $\frac{2}{2}$ = $\frac{2}{10}$ = 0.2

(2) $\frac{6}{25}$ × $\frac{4}{4}$ = $\frac{24}{100}$ = 0.24

(3) 2 $\frac{3}{4}$ = 2 + $\frac{75}{100}$ = 2.75

(4) 3 $\frac{9}{10}$ = 3 + 0.9 = 3.9

(5) 1.25 = 1 $\frac{1}{4}$ = $\frac{5}{4}$

(6) 3.29 = 3 $\frac{29}{100}$ = $\frac{329}{100}$

(7) 0.65 = $\frac{65}{100}$ = $\frac{13}{20}$ in simplest form

(8) 5.6 = 5 $\frac{6}{10}$ = 5 $\frac{3}{5}$ = $\frac{28}{5}$

(9) he is incorrect

$\frac{3}{5}$ × $\frac{20}{20}$ = $\frac{60}{100}$ = 0.6 ≠ 3.5
