How To Calculate A Fraction To A Decimal

Converting a fraction to a decimal involves division. The easiest method is to divide the numerator, the top number, by denominator, bottom number. Memorization of some fractions allows quicker calculations, such a 1/4 equals 0.25, 1/5 equals 0.2 and 1/10 equals 0.1.

Step 1

Determine a number that multiplies the denominator to make the denominator equal 10. For example, with the fraction 24/25, the denominator (25) times 0.4 equals 10.

Step 2

Multiply the numerator by the number you multiplied the denominator by in Step 1. In the example, 24 times 0.4 equals 9.6. The new fraction is 9.6/10.

Step 3

Place a decimal in front of the numerator, and erase the denominator. In the example, 0.96.
