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 $\frac{56}{78}$.
