Question

Помогите пожалуйста.
Номер 1, 2.

Answer 1

$a) frac{3}{4} times frac{1}{5} = frac{3}{20}$
$b) frac{7}{20} times 1 frac{1}{3} = frac{7}{20} times frac{4}{3} = frac{28}{60} = frac{14}{30} = frac{7}{15}$
$8 times frac{5}{6} = frac{40}{6} = frac{20}{3} = 6 frac{2}{3}$
$2. : a) frac{2}{3} div frac{4}{5} = frac{2}{3} times frac{5}{4} = frac{5}{6}$
$b) frac{3}{8} div 9 = frac{3}{8} times frac{1}{9} = frac{3}{72} = frac{1}{24}$
$3. : { frac{10}{3} }^{3 } = frac{10}{3} times frac{10}{3} times frac{10}{3} = frac{1000}{27} = 37 frac{1}{27}$
