Answer 1

a×b=
$3 \times \frac{2}{5} = \frac{6}{5}$
$7 \times \frac{1}{4} = \frac{7}{4}$
$\frac{3}{5} \times 11 = \frac{33}{5}$

$\frac{3}{4} \times 14 = \frac{42}{4}$
$14 \times \frac{5}{21} = \frac{60}{21}$
$2 \times 2 \frac{1}{3} = 2 \times \frac{7}{3} = \frac{14}{3}$
$3 \frac{2}{5} \times 6 = \frac{17}{5} \times 6 = \frac{102}{5}$
$6 \times 5 \frac{2}{4} = 6 \times \frac{22}{4} = \frac{66}{4}$
$2 \frac{1}{7} \times 4 = \frac{15}{7} \times 4 = \frac{60}{7}$
$8 \times 2 \frac{3}{16} = 8 \times \frac{35}{16} = \frac{280}{16} = \frac{70}{4}$
