в) 7/9×4 1/2
г) 3/7×3 1/3

Answer 1

а)

$1 \frac{1}{5} \times \frac{1}{6} = \frac{6}{5} \times \frac{1}{6} = \frac{1}{5}$

б)

$2 \frac{2}{5} \times \frac{2}{3} = \frac{12}{5} \times \frac{2}{3} = \frac{8}{5} = 1 \frac{3}{5} = 1.6$

в)

$\frac{7}{9} \times 4 \frac{1}{2} = \frac{7}{9} \times \frac{9}{2} = \frac{7}{2} = 3 \frac{1}{2} = 3.5$

г)

$\frac{3}{7} \times 3 \frac{1}{3} = \frac{3}{7} \times \frac{10}{3} = \frac{10}{7} = 1 \frac{3}{7}$
