Question

Solving for proportions

Answer 1

1. c=72/15

2. y=4

3. k=-37/4

4.d=6

Explanation:

1. c/6=12/15

Cross multiply. 72=15c.

Dividing by 15, we get C=72/15.

2. 21/7=3. So, 12/y=3. Solving for y, we get y=4.

3. -37/24=k/6

24/6=4. So, -37/k must equal 4.

-37/k=4

-37=4k

k=-37/4

4.

40/8=5. That means that 30/d=5

30=5d

d=6

Done!
