Question

(4 целых 1/6у +11 целых 1/4)* 4/15= 2/3у+ 5 целых 2/3

Answer 1

$(4frac{1}{6}y + 11frac{1}{4}) * frac{4}{15} = frac{2}{3}y + 5frac{2}{3}\ \ (frac{25}{6}y + frac{45}{4}) * frac{4}{15}=frac{2}{3}y+frac{17}{3}\ \ frac{10}{9}y + 3 = frac{2}{3}y + frac{17}{3}\ \ frac{10}{9}y + 3 - frac{2}{3}y - frac{17}{3}=0\ \ frac{4}{9}y - frac{8}{3} = 0\ \ frac{4}{9}y = frac{8}{3}\ \ y = frac{8}{3} * frac{9}{4}\ \ y = 6$
