A proportion is a name we give to a statement that two ratios are equal. It can be written in two ways: two equal fractions or using a colon.

This lesson will look at an example problem involving direct variation. This lesson will give an explanation of how to use proportions and direct variation to solve for x with a step by step look to better explain the concept.

The ratio is the relationship of two numbers. A rate is a little bit different than the ratio, it is a special ratio. It is a comparison of measurements that have different units, like cents and grams. A unit rate is a rate with a denominator of 1.
