# How to Convert a Mixed Fraction

By eHow Education Editor

A mixed fraction is a whole number combined with a fraction. For example, 2 3/4 is a mixed fraction. The number 2 is the whole number, the number 3 is the numerator (upper fraction), and the number 4 is the denominator. Sometimes, when working on mathematical problems, you need to convert the mixed fraction into one fraction, and not a whole number plus a fraction.

Jot down the mixed fraction on a piece of scrap paper. Use a pencil with an eraser when you convert the fraction, since you might have a mistake or two to fix.

Multiply the whole number by the denominator. For this example, use the number above: 2 3/4. Multiply the number 2 (the whole number) by the number 4 (the denominator). This gives you 8.

Add the numerator to your answer in the previous step. In this case, add the number 3 (numerator) to 8 (the answer from the previous step). This gives you 11.

Write your converted fraction. Use the answer from the previous step as your new numerator and the original denominator for your new fraction. Using the example, 11 is the new numerator and 4 the denominator. Your converted fraction, or improper fraction, is 11/4.
