Question

The rectangle on the right is a scaled copy of the rectangle on the left. Identify the scale factor. Express your answer as a whole number or fraction in simplest form.

Answer 1

scale factor is 3/2

Explanation:

to find scale factor, new image divided by original image.

Make sure you rotate the image on the right so it matches the image on the left. 3 corresponds to 9/2 and 5 corresponds to 15/2.

`(9)/(2)` ÷
`(3)/(1) \\`

`(9)/(2)` ×
`(1)/(3)`

`(9)/(6)`

reduce

`(3)/(2)`
