Question

Помогите пожалуйста

Answer 1

5)
$2 frac{2}{5} times frac{5}{6} = frac{12}{5} times frac{5}{6} = 2$
$frac{3}{4} times 1 frac{2}{3} = frac{3}{4} times frac{5}{3} = frac{5}{4} = 1 frac{1}{4}$
$2 - 1 frac{1}{4} = 1 frac{4}{4} - 1 frac{1}{4} = frac{3}{4}$
6)
$frac{45}{28} times frac{7}{9} = frac{5}{4} = 1 frac{1}{4}$
$frac{14}{25} times frac{5}{7} = frac{2}{5}$
$1 frac{1}{4} + frac{2}{5} = 1 frac{5}{20} + frac{8}{20} = 1 frac{13}{20}$
