Question
What should be added to $7\frac{3}{5}$ to get 18?
✓
Answer
For finding the required fraction, we have to subtract $7\frac{3}{5}$ from 18
$\therefore$ Required number $=18-7\frac{3}{5}=\frac{18}{1}-\frac{38}{5}$
$=\frac{90}{5}-\frac{38}{5}=\frac{90-38}{5}$
$=\frac{52}{5}=10\frac{2}{5}$
$\therefore10\frac{2}{5}$ should be added.
