- $$ \frac{2\frac{7}{12}}{6\frac{1}{5}} = \frac{y}{2,2} $$
$$ \frac{\frac{31}{12}}{\frac{31}{5}} = \frac{y}{2,2} $$
$$ \frac{31 \cdot 5}{12 \cdot 31} = \frac{y}{2,2} $$
$$ \frac{5}{12} = \frac{y}{2,2} $$
$$ y = \frac{5 \cdot 2,2}{12} = \frac{5 \cdot 22}{12 \cdot 10} = \frac{11}{12} = 0,91(6) $$
- $$ \frac{2\frac{3}{4}}{4\frac{1}{8}} = \frac{1,6}{t} $$
$$ \frac{\frac{11}{4}}{\frac{33}{8}} = \frac{1,6}{t} $$
$$ \frac{11 \cdot 8}{4 \cdot 33} = \frac{1,6}{t} $$
$$ \frac{2}{3} = \frac{1,6}{t} $$
$$ t = \frac{1,6 \cdot 3}{2} = 0,8 \cdot 3 = 2,4 $$
Ответ: 1) 0,91(6); 2) 2,4
