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 \(\frac{3}{20}\).
Hope that helped! =)
