Question

Patty measured the elementary school and made a scale drawing. The scale she used was 7 centimeters = 1 meter

What is the drawing's scale factor?

Simplify your answer and write it as a ratio, using a colon.​

Answer 1

Write the scale of the drawing as a fraction. Put the shorter length in the numerator.

`(7 \: cm)/(1 \: cm) \\`

First convert the denominator to the same units as the numerator. Write an equivalent fraction with centimeters in the denominator. Since 1 meter is equal to 100 centimeters, multiply the denominator by 100 to get centimeters in the denominator.

`(7 \: cm)/(100 \: cm) = \: (7)/(100) \\`

Write the scale factor as a ratio, using a colon

7/100 → 7:100

The scale factor is 7:100.
