Answer 1

Ответ:

1)

$\frac{7}{8} x = \frac{5}{16} \\ x = \frac{5}{16} \times ( \frac{8}{7} ) \\ x = \frac{5 \times 8}{16 \times 7} \\ x = \frac{40}{112} \\ x = \frac{5}{14} =$

2)

$\frac{8}{24} \div x = \frac{5}{10} \\ 10 \times ( \frac{8}{24} ) = x + 5 \\ 10 \times ( \frac{1}{3} ) = x \times 5 \\ \frac{10}{3} = x \times 5 \\ x \times 5 = \frac{10}{3} \\ x = \frac{ \frac{10}{3} }{5} \\ x = \frac{10}{ 3\times 5} \\ x = \frac{10}{15} \\ x = \frac{2}{3}$

3)

$x \div \frac{5}{12} = 6 \\ x = 6 \times ( \frac{5}{12} ) \\ x = \frac{6 \times 5}{12} \\ x = \frac{30}{12} \\ x = \frac{5}{2} = 2 \frac{1}{2} = 2.5$

4)

$x \times 12 = \frac{8}{5} \\ x \frac{ \frac{8}{5} }{12} \\ x = \frac{8}{5 \times 12} \\ x = \frac{8}{60} \\ x = \frac{2}{15}$

5)

$x \times \frac{5}{3} = 8 \\x = 8 \times ( \frac{3}{5} ) \\ x = \frac{8 \times 3}{5} \\ x = \frac{24}{5 } = 4 \frac{4}{5} = 4.8$
