Question

Write the fraction $\frac{215}{100}$ as decimal .

Answer 1

Writing the fraction as decimal:

Count the number of zeros in the denominator of the fraction and place the decimal point in the numerator after as many digits from the right, as the number of zeros counting from right to left.

$\Rightarrow \frac{215}{100}=2.15$

Only two zeros in the denominator so place the decimal point after two digits from the right in the numerator,

Hence , $\frac{215}{100}$ is expressed as decimal as $2.15$ .
