Add and Subtract Fractions Online practice for grades 3-7
On this page, you can practice addition and subtraction of fractions. Each practice set will automatically include both
addition and subtraction problems.
The options are:
You can limit the fractions in the problems to like fractions (fractions with the same denominator), for example: 1/6 + 4/6.
You can limit the script to use only proper fractions—fractions that are less than 1. With this option, the script will make
problems such as 1/4 + 2/5, but will not make problems such as 8/5 − 4/5.
When you choose problems that use simplified fractions, the script will only include fractions in the problems that are in lowest terms. For example,
you could get a problem such as 5/6 + 3/5, but you would not see 2/4 + 6/8.
The last option, when chose, allows or accepts answers to not be in lowest terms. In other words, the script will accept an
answer such as 8/10.
Note: ALL answers have to be given as mixed numbers, when possible. In other words, your answer cannot be left as an improper fraction.
