The Subtracting fractions with unlike denominators exercise appears under the 5th grade (U.S.) Math Mission, 7th grade (U.S.) Math Mission, Arithmetic essentials Math Mission, Pre-algebra Math Mission and Mathematics I Math Mission. This exercise teaches users to correctly identify and subtract fractions without like denominators.
Types of Problems[]
There is one type of problem in this exercise:
- Subtracting with unlike denominators: This type of problem gives users a subtraction problem with two fractions. Both fractions have unlike denominators and the user has to correctly multiply of divide to make the denominators even before subtracting.
Strategies[]

If students are looking to gain more points, this is a good exercise to receive speed badges or persistence badges in.
Real-life Applications[]
- Fractions appear in every day media to show information to consumers.
- Fractions are used in real life in many different ways, but they are most commonly used in the cooking, construction and science industries.
