Question

знайдіть частку 1) 1 7/11 : 9/22 2) 2 2/3 : 2 2/7 ​

Answer 1

Ответ:

$1 \frac{7}{11} \div \frac{9}{22} = \frac{18}{11} \times \frac{22}{9} = \frac{2}{1} \times \frac{2}{1} = 4$

$2 \frac{2}{3} \div 2 \frac{2}{7} = \frac{8}{3} \div \frac{16}{7} = \frac{8}{3} \times \frac{7}{16} = \frac{1}{3} \times \frac{7}{2} = \frac{7}{6} = 1 \frac{1}{6}$
