Lesson objective: Create and solve equations using equivalent forms of percents such as decimals and fractions.

This lesson helps to build procedural skill with setting up and solving equations using equivalent forms of percents such as decimals and fractions. Double number lines are used here because they support the development of multiplicative reasoning. This work develops students' understanding that we can use equations with equivalent forms of percents such as fractions and decimals to solve problems.

Students engage in Mathematical Practice 2 (Reason abstractly and quantitatively) as they work with the relationships between quantities and percents using equations.

**Key vocabulary:**

- equation
- percent
- fraction
- decimal
- double number line
