Question
Write the following as decimals: $25\frac{1}{2}$
✓
Answer
$25\frac{1}{2}=25+\frac{1}{2}$ To write in decimal,
we need to make the denominator $10$ by multiplying it by a number.
But, to maintain the value of the fraction,
we should also multiply the numerator by the same number.
Thus we get, $=25+\frac{1\times5}{2\times5}$
$=25+\frac{5}{10}$
$=25.5$
