Question
Write the following as decimals: $40\frac{2}{5}$
✓
Answer
$40\frac{2}{5}+40+\frac{2}{5}$ To write in decimal,
we need to make the denominator $10$ by multiplying it by a number.
But to maintain the value of the fractoin,
we should also multiply the numerator by the same number.
Thus we get, $=40+\frac{2\times2}{5\times2}$
$=40+\frac{4}{10}$
$=40.4$
