Question

Х : (3 2/9 -5/6) = 3 пж срочно​

Answer 1

Решение и ответ:

$\displaystyle x\div\left({3\frac{2}{9}-\frac{5}{6}}\right)=3$

$\displaystyle x\div\left({3\frac{4}{{18}}-\frac{{15}}{{18}}}\right)=3$

$\displaystyle x\div\left({2\frac{{22}}{{18}}-\frac{{15}}{{18}}}\right)=3$

$\displaystyle x\div2\frac{7}{{18}}=3$

$\displaystyle x=2\frac{7}{{18}}\cdot 3$

$\displaystyle x=\frac{{43}}{{18}}\cdot 3$

$\displaystyle x=\frac{{43}}{6}=7\frac{1}{6}$

Answer 2

Ответ:

x: (3 2/9 - 5/6)=3

3 2/9 - 5/6 = x : 3

x: 3=2 7/18

x= 2 7/18 × 3

x= 7 1/6
