How do I solve this problem

Brums [2.3K]

Answer:

a =9

b= 28

Step-by-step explanation:

The parts of the ratio must be equal

5:7:a = 20:b:36

How do we get from 5 to 20

We multiply by 4

So multiply the first by 4

5*4:7*4:a*4 = 20:b:36

Ratio 1

5*4 =20 true

Ratio 2

7*4 =b

28 = b

Ratio 3

4a = 36

Divide by 4

4a/4 = 36/4

a = 9
