A. 4 in.
B. 6 in.

D. 9 in.

Answer 1

You can get the ratio of the sizes by dividing the painting width by the postcard width... this tells you the scale factor

Answer 2

So the answer's c?

Answer 3

No. 8 is the scale factor. So if the postcard width is 3 in , we do 3*8 to get 24 in, the width of the painting.

You want to apply the same idea for how long it is. If the painting 32 in long, how long is the postcard?
