Question

Решите уравнение : 2 1/4 : 1 1/2 =х:3/7

Answer 1

$2 \frac{1}{4} \div 1 \frac{1}{2} = x \div \frac{3}{7} \\ \\ \frac{9}{4} \times \frac{2}{3} = x \times \frac{7}{3} \\ \\ \frac{3}{2} = \frac{7}{3} x \\ \\ x = \frac{3}{2} \div \frac{7}{3} \\ \\ x = \frac{3}{2} \times \frac{3}{7} \\ \\ x = \frac{9}{14}$

Ответ: х = 9/14

Answer 2

Ответ:

$2\frac{1}{4} \div 1 \frac{1}{2} = x \div \frac{3}{7} \\ \frac{2 \times 4 + 1}{4} \div \frac{1 \times 2 + 1}{2} = x \div \frac{3}{7} \\ \frac{9}{4 } \div \frac{3}{2} = x \div \frac{3}{7} \\ \frac{9}{4} \times \frac{2}{3} = x \div \frac{ 3}{7} \\ \frac{3}{2} = x \div \frac{3}{7 } \\ x \div \frac{3}{7} = \frac{3}{2} \\ x = \frac{3}{2} \times \frac{3}{7} \\ x = \frac{9}{14}$
