Question

(3- четыри седмых)*x=пять целых две третих

Answer 1

(3 - 4/7) *x = 5 2/3
(21-3)/7 *x =17/3
17/7 *x =17/3
x =17/3 *7/17 =7/3 = 2 1/3
x = 2 1/3

Answer 2

$(3- \frac{4}{7})*x=5 \frac{2}{3}$
$( \frac{21}{7}- \frac{4}{7})*x= \frac{17}{3}$
$\frac{17}{7}*x= \frac{17}{3}$
$x= \frac{17}{3}* \frac{7}{17}= \frac{7}{3}=2 \frac{1}{3}$
