Question

Find the scale factor.

0.3
0.4
0.5
0.6

hint Hint:

A scale factor in math is the ratio between corresponding measurements of an object and a representation of that object.

The correct answer is: 0.5

Length of A is 6 units, and the length of B is 3 units.
Scale factor, $k equals space fraction numerator l e n g t h space o f space n e w space p r o d u c t over denominator l e n g t h space o f space o l d space p r o d u c t end fraction space equals space 3 over 6 equals 1 half equals 0.5$
So, it’s a reduction.
