This seventh-grade math worksheet provides practice for solving proportions using cross products and inverse operations. The one-page worksheet starts with an example problem that demonstrates how to solve for a variable in two equivalent ratios. Students will then use this knowledge to solve nine practice problems, each with variables in the numerator or denominator of a ratio set equal to ratios made up of two- and three-digit numbers. Solving proportions is an essential skill for understanding proportional relationships in real-world scenarios and serves as a fundamental skill for higher-level math concepts.
