Question

(1 5/8-24/7)*5,4х=9 1/2+ 2 1/4. срочно​

Answer 1

$( 1frac{5}{8} - frac{24}{7} ) times 5.4x = 9 frac{1}{2} + 2 frac{1}{4} \ \ (1 frac{5}{8} - 3 frac{3}{7} ) times 5.4x = 9.5 + 2.25 \ \ ( 1frac{35}{56} - 3 frac{24}{56} ) times 5.4x = 11.75 \ \ ( frac{91}{56} - 1 frac{136}{56} ) times 5.4x = 11.75 \ \ - 1 frac{45}{56} times 5.4x = 11.75 \ \ 5.4x = - frac{1175 times 56}{100 times101 } \ \ 5.4x = - 6 frac{52}{101} \ \ x = - frac{10 times 658}{54 times 101} \ \ x = - 1 frac{563}{2727}$
