Chapter 7: Problem 37

What is a proportion? Give an example with your description.

Short Answer

Expert verified
A proportion refers to a statement that two ratios are equal. For instance, the proportion \(\frac{2}{5} = \frac{x}{10}\) can be solved to find x = 4.

Step by step solution

01

Proportion Definition

A proportion is a name we give to a statement that two ratios are equal. It can be used to solve for a missing value when equivalent fractions are set equal to each other.
02

Giving an Example

Here's an example of a proportion: \(\frac{2}{5} = \frac{x}{10}\)
03

Explain the Example

In the example, we have two fractions set equal to each other. This makes a proportion. The value of x can be solved by cross-multiplication such that \(2*10 = 5*x\), leading to x = 4. The proportion therefore helps to solve for unknown values in equivalent fractions.
