Grade 7 | Unit 1 | Lesson 5: The Size of the Scale Factor | Practice Problems

Rectangles P, Q, R, and S are scaled copies of one another. For each pair, decide if the scale factor from one to the other is greater than 1, equal to 1, or less than 1. Description: Four rectangles, labeled P, Q, R, and S. Each rectangle is a scaled copy of one another. Ranked in order from least to greatest, the area of the rectangles are as follows: the area of P is equal to S, which are less than the area of Q, which is less than the area of R.

• from P to Q

• from Q to S

• from Q to R

• from P to R

• from S to P
