Решите уравнение:2:m= 2 1/7:3 4/7

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