Exercise 33 Page 610

Create a proportion using the given scale.

10.5 inches

Practice makes perfect
We are given that the scale of a drawing of a school's floor is 6inch: 100feet. To find the corresponding length of the scale drawing, we will create a proportion. 6/100=length in drawing/actual lengthSince we know that the actual length is 175 feet, we will substitute this value into the proportion. Let x represent the length in the drawing. 6/100=x/175 Now we will solve the above proportion for x using cross multiplication.
6/100=x/175
6* 175=100* x
â–Ľ
Solve for x
1050=100x
1050/100=x
10.5=x
x=10.5
The corresponding length of the scale drawing is 10.5 inches.
