Introduction to Adding and Subtracting Fractions With Common Denominators
In math class, Mike's teacher shares that 1/8 of the students received an A on the latest test and 3/8 of the students received a B. Mike wants to figure out what fraction of the class got either an A or B on the test. To do this, he'll have to add fractions. In this section, we'll use models to explore how to add and subtract fractions with common denominators.Learning Outcomes
By the end of this section, you will be able to:- Model fraction addition
- Add fractions with a common denominator
- Model fraction subtraction
- Subtract fractions with a common denominator
