Answer 1

Пошаговое объяснение:

3/14х = 1

х = 1 : 3/14

х = 1 * 14/3

х = 14/3

х = 4 2/3

5/12х = 1/2

х = 1/2 : 5/12

х = 1/2 * 12/5

х = 1/1 * 6/5

х = 6/5

х = 1 1/5

4/9х = 2 2/3

х = 2 2/3 : 4/9

х = 8/3 * 9/4

х = 2/1 * 3/1

х = 6/1

х = 6

1 7/10х = 6 4/5

17/10х = 34/5

х = 34/5 : 17/10

х = 34/5 * 10/17

х = 2/1 * 2/1

х = 4/1

х = 4

Answer 2

$\frac{3}{14} x = 1 \\ x = 1 \div \frac{3}{14} \\ x = \frac{14}{3} \\ x = 4 \frac{2}{3}$

$\frac{5}{12} x = \frac{1}{2} \\ x = \frac{1}{2 } \div \frac{5}{12} \\ x = \frac{1 \times 12}{2 \times 5} \\ x = \frac{6}{5} \\ x = 1 \frac{1}{5} \\ x = 1.2$

$\frac{4}{9} x = 2 \frac{2}{3} \\ x = 2 \frac{2}{3} \div \frac{4}{9} \\ x = \frac{8 \times 9}{3 \times 4} \\ x = 2 \times 3 \\ x = 6$

$1 \frac{7}{10} x = 6 \frac{4}{5} \\ x = 6 \frac{4}{5} \div 1 \frac{7}{10} \\ x = \frac{34 \times 10}{5 \times 17} \\ x = 2 \times 2 \\ x = 4$
