Question

обчисли а) 2/5 : 1/10 б) 1/3 : 1/6 в) 1/9 : 1/3 г) 6/5 : 3 д) 5 : 10/9 е) 10 : 1/2 срочнооооо!!!!! Даю 20 баллов

Answer 1

Ответ: а) 2/5 : 1/10 = 2/5 * 10/1 = 20/5 = 4

б) 1/3 : 1/6 = 1/3 * 6/1 = 6/3 = 2

в) 1/9 : 1/3 = 1/9 * 3/1 = 3/9 = 1/3

г) 6/5 : 3 = 6/5 * 1/3 = 6/15 = 2/5

д) 5 : 10/9 = 5 * 9/10 = 45/10 = 9/2

е) 10 : 1/2 = 10 * 2/1 = 20

Answer 2

Ответ:

$1)4 \\ 2)2 \\ 3) \frac{1}{3} \\ 4) \frac{2}{5} \\ 5) \frac{9}{2} \\ 6)20$

Пошаговое объяснение:

$\frac{2}{5} \div \frac{1}{10 } = \frac{2}{5} \times1 0 = 2 \times 2 = 4$

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

$\frac{1}{9} \div \frac{1}{3} = \frac{1}{9} \times 3 = \frac{1}{3}$

$\frac{6}{5} \div 3 = \frac{6}{5} \times \frac{1}{3} = \frac{2}{5}$

$5 \div \frac{10}{9} = 5 \times \frac{ 9}{10} = \frac{9}{2}$

$10 \div \frac{1}{2} = 10 \times 2 = 20$
