To FIND :

The number that should be multiplied by \frac{-7}{26} to get the product \frac{56}{78}?

Solⁿ :

Let the unknown number be x.

Now,

=  > \frac{ - 7}{26}  \times x =  \frac{56}{78}

=  >  \frac{ - 7x}{26}  =  \frac{56}{78}

=  >  - 7x =  \frac{56}{78}  \times 26

=  >  - 7x = { \cancel{ \frac{1456}{ \cancel{78}}}}  =  \frac{56}{3}

=  >  - x =  \frac{56}{3}  \div 7

=  >   - x = \frac{56}{3}  \times  \frac{1}{7}

=  >  - x =  \frac{8}{3}

=  > x =  \frac{ - 8}{3}

\frac{ - 8}{3}

Hence, \frac{ - 8}{3} should be multiplied by \frac{-7}{26} to get the product \frac{56}{78}.

HOPE it is helpful....
