Question

What should be added to -6/11 to make it 9/13​

Answer 1

Answer: $\frac{177}{143}$

Step by step:

$\frac{-6}{11} + x = \frac{9}{13}$

x = $\frac{9}{13} +\frac{6}{11}$

x = $\frac{99 + 78}{143}$

x = $\frac{177}{143}$

Therefore, you need add $\frac{177}{143}$ to make it $\frac{9}{13}$.

Hope this helps :)
