Question

9. Raul's teacher purchases two rectangular paintings. The dimensions of the first painting are proportional to the

Answer 1

Answer:

(c) 9 3/5

Step-by-step explanation:

This is a ratio question. We can work with the dimensions as fractions and solve through cross-multiplication.

Dimensions of the first painting:

8/20 in.

Possible dimensions of the second painting:

24/x in.

x/24 in.

There are two options, because the given 24 inches may be either a length or width of the painting.

Now, we can use cross-multiplication to try to find x in both scenarios.

Scenario #1

8/20=24/x

8x=480

x=60 in.

60 in. is not an answer. Let's try the other scenario.

Scenario #2

8/20=x/24

192=20x

9.6 in.=x

9.6 can also be written as 9 3/5, which is option C.
