This lesson is for students in grades 5 through 7.
The objectives are:
Identify a proportion.
Test an equation to see if it is a true proportion and find the missing term in a proportion.
Use proportions to solve problems:
Find reduced scale sizes for a set of structures (skyscrapers, bridges, and tunnels).
Find proportional amounts of ingredients for a recipe.
A ratioChic Weaving Made Size Huarache Bruno Unworn Street NOS 48023 Valenti in Shoes Navy Woven 10 Pumps Style Leather 1980s Brazil Zrw8Zq a comparison of two quantities. The ratio of dogs to cats is 3 to 2. The ratio of gerbils to guinea pigs is 9 to 6. A proportion is a comparison of two quantities. The ratio of 3 to 2 is the same as the ratio of 9 to 6.

For every three animals of one species there are two of the other species. These two ratios are equal to each other: This is a proportion.
3/2 = 9/6
Hey! That look's like a pair of equivalent fractions. Right, fractions are rational numbers. When two fractions represent the same amount, they are equivalent fractions. Two ratios that are equivalent to each other are a proportion.
How do you know if two ratios are a proportion?
An equation such as 5/8 = 60/96 is a proportion if the two ratios are equivalent to each other. Either reduce one ratio to lowest terms or raise the other ratio to equivalent terms.
5 x 12 = 60 8 x 12 = 96 therefore 5/8 = 60/96
60 / 12 = 5 96 / 12 = 8 therefore 5/8 = 60/96
Another way to test a proportion for is to use cross multiplication.
7:3 = 28:12
Multiply 7 by 12. 7 x 12 = 84
Multiply 3 x 28. 3 x 28 = 84
Both products are 84, therefore 7:3 = 28:12
What if one term in a proportion is missing? How can you find the missing term?
One way to find a missing term in a proportion is to find the equivalent fraction.
4/9 = 96/?
4 x 24 = 96 therefore 9 x 24 = 216.
4/9 = 96/216
A second way to find a missing term in a proportion is to use cross multiplication.
27/5 = 8/?
27 x = 5 . 8
27 x = 40
x = 40/27
x = 1.48
There are many real-life applications for proportions. Some of these are:
Maps, blueprints, and scale models. An appropriate ratio, or scale, is chosen. Large objects or areas can then be shown in a considerably smaller size or space. Movies frequently use scale models of ship, planes, buildings.
Medicine dosages are frequently related to the weight of the patient, so the dosage must be increased proportionally to weight.
Recipes or formulas may be increased or decreased by using proportions.
Economic and sociological predictions based on the relationship of two quantities.

The scale you will use is 50 feet = 1inch; this is the ratio of 50/1. Round all answers to the nearest hundredth. To find the actual height or length, click on the name of the structure. Remember to keep the order of the terms the same in both proportions.
