Step 1
Given: 128 cars are washed in 3 hours.
So, proportions:
3128=8n
Variable n cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 128 n, the least common multiple of 128, n.
3n=128×8
Multiply 128 and 8 to get 1024.
3n=1024
Divide both sides by 3.
n=10243
=34113341.333333333
