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