Question

Nadia is making a copy of an image on the copy machine. She needs to enlarge it, and decides to enlarge it by a scale factor of three. If one side of the original is 1 1/2 in., how big is that same side after she makes the copy?

Answer 1

`4(1)/(2)in`

Explanation:

We know that one side of the original is

`1(1)/(2)in`

Also, the copy machine enlarges the original by a scale factor of three. This means that the enlarged result is three times bigger that the original. Remember that a scale factor multiplies the original measure.

So, the bigger copy would be

`3* 1(1)/(2)in=3 * (3)/(2)=(9)/(2)=4(1)/(2)in`

Therefore, the image changed from
`1(1)/(2)in` to
`4(1)/(2)in`.

Answer 2

The new side will measure;
3/2*3
=9/2
=4.5 inches
