Question

b:7/8=4/11:28/11 решите уравнение

Answer 1

Пошаговое объяснение:

$\frac{b}{1} \div \frac{7}{8} = \frac{4}{11} \div \frac{28}{11}$

$\frac{8b}{7} = \frac{4 \times 11}{11 \times 28}$

$\frac{8b}{7} = \frac{1}{7}$

$8b = 1$

$b = \frac{1}{8}$

Answer 2

Ответ:

b÷7/8=4/11×11/28=1/1×1/7

b÷7/8=1/7

b=1/7×7/8=1/1×1/8

b=1/8

1/8÷7/8=1/7

1/8×8/7=1/1×1/7=1/7

1/7=1/7
