Answer:

see below

Step-by-step explanation:

The ratio is 20/16 = 5/4

10/a = 5/4

Using cross products

10*4 = 5a

Divide each side by 5

40/5 = a

8 =a

9/b = 5/4

Using cross products

9*4 = 5b

36 = 5b

Divide each side by 5

36/5 =b

7.2 =b

12/c = 5/4

Using cross products

12*4 = 5c

48 = 5c

Divide each side by 5

48/5 = c

9.6 =c
