Question

Convert the fraction $\frac{3}{8}$ into decimals by making the denominator a multiple of $10$.

Answer 1

$\Rightarrow \frac{3}{8}=\frac{3\times 125}{8\times 125}$ ( Multiply the numerator and denominator by $25$ to make the denominator a multiple of $10$ )

$\Rightarrow \frac{3\times 125}{8\times 125}=\frac{375}{1000}$

$\Rightarrow \frac{375}{1000}=0.375$ ( Since , there are three zeros in denominator so the decimal point will be placed after three digit in the numerator moving from right to left )

Thus , the decimal representation of $\frac{3}{8}$ is $0.375$ .
