Question

A scale drawing of a car uses a scale of 2cm =1m. What is the length of the car on the drawing if the actual car measures 4 m?

Answer 1

simply divide 4m by the given scale length of 1m
4/1 = 4

now multiply that by 2cm
4*2 = 8


`8cm`

Answer 2

The answer is 8cm.

Explanation:

The scale drawing uses a ratio of 2cm:1m. If the actual car is 4 meters long, you would multiply 2 by 4 to get 8cm. The actual new ratio on the map is 8cm:4m, which is equivalent to the one in the problem.
