Question

Помогите пожалуйста срочно ​

Answer 1

1)

$\frac{9}{16} - x = \frac{1}{2} \\ x = \frac{9}{16} - \frac{1}{2} \\ x = \frac{9 - 8}{16} = \frac{1}{16}$

2)

$x + \frac{2}{3} = \frac{7}{8} \\ x = \frac{7}{8} - \frac{2}{3} \\ x = \frac{3 \times 7 - 8 \times 2}{24} = \frac{21 - 16}{24} = \frac{5}{24}$

3)

$\frac{1}{2} + x = \frac{23}{24} \\ x = \frac{23}{24} - \frac{1}{2} \\ x = \frac{23 - 12 \times 1}{24} = \frac{23 - 12}{24} = \frac{11}{24}$

4)

$x - \frac{3}{8} = \frac{1}{4} \\ x = \frac{1}{4} + \frac{ 3}{8} \\ x = \frac{4 \times 1 + 2 \times 3}{16} = \frac{4 + 6}{16} = \frac{10}{16} = \frac{5}{8}$
