Here you can find **0.042 as a fraction**, both as decimal fraction and in simplest form as displayed in our converter right below:

0.042 has 3 decimal places, so we put the decimal digits of 0.042, 042, over 1 followed by the number of zeroes equal to the number of decimal places, 3: 042 = 042/1000.

**decimal fraction**= 42/1000

42 is the nominator and 1000 is the denominator. We now check if the decimal fraction is already in the lowest terms by finding the greatest common factor of 42 and 1000, know as gcf of 42 and 1000.

The gcf(42,1000) is 2, so we can conclude that 42/1000 is not 0.042 as a fraction in simplest form. To obtain 0.042 as a fraction in simplest form we have to divide both, the nominator as well as denominator, by the gcf(42,1000):

42/1000 =
