Question

Classify each scale factor as a contraction or expansion drag and drop the choices into the box to complete the table 0.9 ,3/8, -6, 5, 8/5

Answer 1

A scale factor of a dilation is greater than 1, then it is an expansion and if it is less than 1, then it is a contraction.

From the given values, scale factors 0.9, 3/8 -6 refer to a contraction and 5 and 8/5 refer to an expansion.

Example:

Consider any shape with area 40 square units.

Then,

40(0.9) = 36 < 40

40(3/8) = 15 < 40

40(-6) = -240 < 40

So, 0.9, 3/8 and -6 refer to contractions.

Now,

40(5) = 200 > 40 and

40(8/5) = 64 > 40

So, 5 and 8/5 refer to expansions.

Answer 2

Answer:

3/2  - expansion; 1/4  - contraction; 4 - expansion;  0.8  - contraction; -3 - expansion.
