Mary and Linda each made a scarf for their doll. The picture below shows the measurements of each scarf.

Mary's scarf: base - 9cm ; height - 4 cm
Linda's scarf: base - 12 cm ; height - 7cm

Which of the following statements is true?

A.
The scarfs are not proportional because 4 × 9 is not equal to 12 × 7.

B.
The scarfs are not proportional because 9 × 7 is not equal to 12 × 4.

C.
The scarfs are proportional because 4 + 9 = 13 and 12 + 7 = 19.

D.
The scarfs are proportional because 9 + 7 = 12 + 4.

Answer 1

I'm guessing B...

Answer 2

Yep, b.

Answer 3

Set up a proportion
7/12=4/9
cross multiply gives u 7*9=4*12
and that's b
