Direct Variation Word Problems Worksheet With Answers

Introduction

Direct variation word problems are an essential part of the mathematics curriculum. They involve solving equations with one variable in terms of another. The problems can be quite challenging, and require an understanding of the concept of direct variation. This article will explain what direct variation is, and provide a worksheet with answers to help students master this important mathematical concept.

What is Direct Variation?

Direct variation is a type of proportional relationship between two variables. In other words, when one variable increases, the other one also increases at a certain rate. This rate is referred to as the constant of variation. To solve a direct variation problem, you must find the constant of variation and then use it to solve for the unknown variable.
