Question

Решите уравнение: 8,5 - 5/8 * 2,4 = (две целых 3/22 - 2/55) * 0,6 0,45х (7/15 - 5/18) * две целых 11/17

Answer 1

$\frac{8,5- \frac{5}{8} *2,4}{( \frac{7}{15}- \frac{5}{18} )*2 \frac{11}{17} } = \frac{(2 \frac{3}{22}- \frac{2}{55})*0,6}{0,45x}$

$\frac{8.5-1.5}{( \frac{7}{15}- \frac{5}{8} )* \frac{45}{17} } = \frac{( \frac{x47}{22}- \frac{2}{55} )*0.6}{0.45x}$

$\frac{7}{ \frac{42-25}{90}* \frac{45}{17} } = \frac{ \frac{235-4}{110}*0.6}{0.45x}$

$\frac{7}{ \frac{17}{90}* \frac{45}{17} } = \frac{ \frac{231}{110}*0.6 }{0.45x}$

$\frac{7}{ \frac{1}{2} } = \frac{2.1*0.6}{0.45x}$

$14= \frac{1.26}{0.45x}$

$0.45x= \frac{1.26}{14}$

0.45x=0.09

$x= \frac{0.09}{0.45}$

x=0.2
