Question

Classify each scale factor as a contraction or an expansion. Drag and drop the choices into the boxes to complete the table.

Contraction Expansion


3/2
1/4
4
0.8
-3

Answer 1

The answers are

Contraction: 1/3, 0.8

Expansion: 4, -3, 3/2

Step-by-step explanation:

Expansion, everything that is above 1 is considered expansion even if it is a negetive.

Contraction, anything that is below 1 is considered contraction.

Answer 2

The correct answers are: 3/2, expansion; 1/4, contraction; 4, expansion; 0.8, contraction; -3, expansion.

Explanation:
If a scale factor is greater than 1, it is an expansion. This means that both 3/2 and 4 are expansions.

If a scale factor is less than 1, it is a contraction. This means that 1/4 and 0.8 are contractions.

If a scale factor is negative, we treat it as if we would a positive, but it is on the opposite side of the point of enlargement. This means that -3 would still be an expansion.
