Question

how can you write 0.15 in a fraction

Answer 1

In order to write a decimal as a fraction, you simply need to put all the numbers in the decimal as the numerator of the fraction, and then put a multiple of 10 with as many zeros as there are numbers to the right of the decimal point as the denominator.

0.15 = $\frac{15}{100}$

We can reduce our resulting fraction, since both numerator and denominator are divisible by 5.

$\frac{15 / 5}{100 / 5} = \frac{3}{20}$

Which is our final answer.
0.15 written as a fraction is $\frac{3}{20}$.
