Question

3
-2
3/4
1/5

Answer 1

contraction: 1/5 and 3/4 expansion: 1.25, 3, and -2

Explanation:

i took the quiz

Answer 2

Scale factor 1.25 is an expansion since we 'enlarge' the original size 1.25 times

Scale factor 3 is an expansion since we 'enlarge' the original size by 3 times

Scale factor -2 is also an expansion since we 'enlarge' the original size by 2 times but on the opposite direction of the centre of enlargement

Scale factor 3/4 is a contraction since we make the original size 'smaller' by 0.75 times

Scale factor 1/5 is also a contraction since we make the original size 'smaller' by 0.20 times
