Work Step by Step

A great way to turn fractions into decimals is to make the denominator (bottom of the fraction) 100. We multiply 13/20 by 5/5 (this is allowed because 5/5 equals 1) to get 65/100. We now use a straightforward rule. Whenever a number is divided by 100, move the decimal on the number two to the left. We move the decimal on the numerator, 65.0, two to the left to get .65.
