Exercise 49 Page 548

Do both concepts use fractions? Do both concepts involve equations?

See solution.

Practice makes perfect

One thing that ratios and proportions have in common is that both are written using fractions.

Ratio	Proportion
a/b	p/q=r/s

A ratio compares two quantities by dividing them, while a proportion is used to equate two ratios. To solve a problem, ratios allows us to compare quantities, which can then be equated using proportions. Then we can use cross products to solve the proportion.
