Question

Find the length of a picture frame whose width is 3 inches and whose proportions are the same as a 9-inch wide by 12-inch long picture frame.

Answer 1

Explanation:

4 inches

Answer 2

4 inches

Explanation:

We can set up a proportion to find out the length value (assuming x is the length of the frame)

`(3)/(x) = (9)/(12)`

We multiply 12 and 3...

`12\cdot3=36`

And divide by 9...

`36/9=4`

So, the length of the frame is 4 inches.
