Question

Решите пропорцию 6 класс!

Answer 1

$\frac{7 - y}{6} = \frac{5}{9 } \\ \\ 9 \times (7 - y) = 5 \times 6 \\ 63 - 9y = 30 \\ 9y = 63 - 30 = 33 \\ 3y = 11 \\ y = \frac{11}{3} = 3 \frac{2}{3}$

Answer 2

$\frac{7-y}{6}$=$\frac{5}{9}$⇒ 9(7-y)=6*5;

63-9y=30;

9y=63-30;

9y=33;

y=33:9;

y=$3\frac{6}{9}$=$3\frac{2}{3}$
