Question

by what number should 5/7 be divided to get-3/14​

Answer 1

Answer:

$\frac{-20}{21}$

Step-by-step explanation:

Let the no. be $x$.

So, $\frac{5}{7}$ ÷ $x$ = $\frac{-3}{4}$

=> $\frac{5}{7}$ = $\frac{-3}{4}$ X $x$

=> $\frac{5}{7}$ = $\frac{-3x}{4}$

By cross-multiplication: -

=> $5$ × $4 = -3x$ × $7$

=> $20=-21x$

=> $\frac{-20}{21} = x$

Hence, divide $\frac{5}{7}$ by $\frac{-20}{21}$ to get $\frac{-3}{4}$.
