Question

Complete Syd's work to find the scale factor.

Scale factor = ? (Fill in the blank)

A) 2.5
B) 3.5
C) 5.5
D) 7.5

Answer 1

To find the scale factor, you need to compare the scale length to the actual length. Therefore the correct option is A). 2.5.

Step-by-step explanation:

To find the scale factor, we need to compare the scale length to the actual length. Let's look at an example: Example: A metal pipe is 2.5 meters long. Josh wants to make a scale drawing of the pipe with a scale factor of 1/100. To find the length in centimeters, we can use the scale factor: Scale factor = 1/100 = 0.01. Therefore, the length of the metal pipe in the drawing will be 0.01 * 250 (converted from meters to centimeters) = 2.5 centimeters. Therefore the correct option is A). 2.5.
