Question
What should be added to $\frac{-5}{11}$ so as to get $\frac{26}{33}?$
✓
Answer
Let the required number be x
$-\frac{5}{11}+\text{x}=\frac{26}{33}$
$\text{x}=\frac{26}{33}-\frac{-5}{11}$
$\text{x}=\frac{26}{33}-\frac{5\times3}{11\times3}$
$\text{x}=\frac{26}{33}-\frac{-15}{33}$
$\text{x}=\frac{26+15}{33}$
$\text{x}=\frac{41}{33}$
The required number is $\frac{41}{33}$
