Решите уравнение:2:m= 2 1/7:3 4/7

2 : m = $2\frac{1}{7} : 3 \frac{4}{7}$
2 × $3 \frac{4}7}$ = m × 2 \frac{1}{7}[/tex]
2 × $\frac{25}{7}$ = m× $\frac{15}{7}$
$\frac{50}{7}$ = $\frac{15}{7} m$
m = $\frac{50}{7} : \frac{15}{7} = \frac{50}{7}$ × $\frac{7}{15}$ = $\frac{10}{3} = 3 \frac{1}{3}$

2 : $3 \frac{1}{3} = 2 \frac{1}{7} : 3 \frac{4}{7}$
