Lesson 11: Practice Problems
Problem 1
A scale drawing of a car is presented in the following three scales. Order the scale drawings from smallest to largest. Explain your reasoning. (There are about 1.1 yards in a meter, and 2.54 cm in an inch.)
1 in to 1 ft
1 in to 1 m
1 in to 1 yd
Problem 2
Which scales are equivalent to 1 inch to 1 foot? Select all that apply.
1 to 12
100 to 0.12
5 to 60
36 to 3
9 to 108
Problem 3

Problem 6 From Unit 1 Lesson 5
Figures R, S, and T are all scaled copies of one another. Figure S is a scaled copy of R using a scale factor of 3. Figure T is a scaled copy of S using a scale factor of 2. Find the scale factors for each of the following:
From T to S
From S to R
From R to T
From T to R
