Students use the pyramid method to solve percent problems. The pyramid grid provides a visual way to set up the equation.

Learners follow steps to add fractions with different denominators. They also review fraction concepts, do a drag-and-drop exercise involving fraction terms, and add fractions with common denominators.

In this animated and interactive object, learners view two examples of how to subtract fractions with unlike denominators and then work five similar problems.

In this learning activity you'll explore how to change a decimal to a fraction and learn a method to visually check the fraction for accuracy.
