Question
Waht should be added to $5\frac{3}{7}$ to get 12?
✓
Answer
We have,
$5\frac{3}{7}=\frac{38}{7}$
Let x be the number added to $\frac{38}{7}$ to get 12
Therefore,
$\text{x}+387=12$
$\Rightarrow\text{x}=12-\frac{38}{7}$
$\Rightarrow\text{x}=\frac{12\times7-38}{7}$
$\Rightarrow\text{x}=\frac{84-38}{7}$
$\text{x}=\frac{46}{7}$
