What you’ll learn to do: Add and subtract fractions with common denominators
In math class, Mike’s teacher shares that [latex]\Large\frac{1}{8}[/latex] 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’llĀ use models to explore how to add and subtract fractions with common denominators.
