Question

1 3/4×2 4/7:4 1/2+2 2/5:9/10×3/8
​

Answer 1

Пошаговое объяснение:

1).

$\frac{3}{4} \times 2 = \frac{3 \times 2}{4} = \frac{6}{4} = \frac{3}{2} = 1 \frac{1}{2}$

2).

$\frac{4}{7} \div 4 = \frac{4}{7} \div \frac{4}{1} = \frac{4}{7} \times \frac{1}{4} = \frac{1}{7}$

3).

$\frac{1}{2} + 2 = 2 \frac{1}{2}$

4).

$\frac{2}{5} \div \frac{9}{10} \times \frac{3}{8} = \frac{2}{5} \times \frac{10}{9} \times \frac{3}{8} = \frac{2}{3 \times 4} = \frac{1}{6}$
