Question

Решите уравнения с дробями

1) 7|9:x=7|18
2) x:1|2=1|2
3) 12|25:x=3|5

Answer 1

$\frac{7}{9} /x= \frac{7}{18} \\ x= \frac{7}{9}/ \frac{7}{18} \\ x= \frac{7}{9}* \frac{18}{7} \\ x= \frac{2}{1}$

 $x/ \frac{1}{2} = \frac{1}{2} \\ x= \frac{1}{2}* \frac{1}{2} \\ x= \frac{1}{4}$

Answer 2

1) X = ( 7/9 ) : ( 7/18 ) = 18/9 = 2 ; 2) X = ( 1/2 ) * ( 1/2 ) = 1/4 2) X = ( 12/25 ) : ( 3/5 ) = 12/15 = 3/5 = 0,6
