Question

Figure B is a scale image of Figure A, as shown.

Answer 1

`\bold{2(4)/(5)}` or 2.8

Explanation:

Scale factor is the original value multiplied by a number. So if we are looking for the scale factor, and it is multiplication, we should do the opposite action. The inverse operation for multiplication is division.

Step 1: Divide 7 by 2.5

`(7)/(2.8)`

`7/2.5=\bold{2.8}`

Now, we can also confirm if this is correct. Simply multiply the answer to the original image.

`2.8*2.5=7`

Therefore, the scale factor is 2.8, or
`\bold{2(4)/(5)}` in fraction form.
