Question

1) 1/3 x = 15/18

2) x : 3 4/15 = 5/14

помогите пожалуйста

Answer 1

Ответ:

$\frac{1}{3} x = \frac{15}{18} \\ x = \frac{15}{18} \div \frac{1}{3} = \frac{15}{18} \times \frac{3}{1} \\ x = \frac{5}{2} = 2 \frac{1}{2} \\ \\ x \div 3 \frac{4}{15} = \frac{5}{14} \\ x = \frac{5}{14} \times 3 \frac{4}{15} = \frac{5}{14} \times \frac{49}{15} \\ x = \frac{7}{6} = 1 \frac{1}{6}$
