Answer:C.40

Step-by-step explanation:

Answer:

C. 40

Step-by-step explanation:

18/x = 45/100, x is the value we are looking for

18/x = 45/100

1800/x = 45                   multiply both sides by 100

1800 = 45x                    multiply both sides by x

40 = x                             divide both sides by 45
