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

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

Answer 2

Answer:

$4\frac{1}{2}in$

Step-by-step explanation:

We know that one side of the original is

$1\frac{1}{2}in$

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

$3\times 1\frac{1}{2}in=3 \times \frac{3}{2}=\frac{9}{2}=4\frac{1}{2}in$

Therefore, the image changed from $1\frac{1}{2}in$ to $4\frac{1}{2}in$.
