Question

D)1 1/2 * x = 3 4/5 F)x : 2 2/3 =1 1/7 БЕЗ ПОДРОБНОГО РЕШЕНИЯ БАН

Answer 1

Пошаговое объяснение:

D).

$1 \frac{1}{2} \times x = 3 \frac{4}{5}$

$1 \frac{1}{2}x = 3 \frac{4}{5}$

$\frac{3}{2}x = \frac{19}{5}$

$x = \frac{19}{5} \div \frac{3}{2}$

$x = \frac{19}{5} \times \frac{2}{3}$

$x = \frac{38}{15}$

F).

$x \div 2 \frac{2}{3} = 1 \frac{1}{7}$

$x = 1 \frac{1}{7} \times 2 \frac{2}{3}$

$x = \frac{8}{7} \times \frac{8}{3}$

$x = \frac{64}{21}$

$x = 3 \frac{1}{21}$
