Final answer:
To solve for x when given a percent proportion
Step-by-step explanation:
To solve the percent proportion, we can set up the equation:
60 = 0.15x
We want to solve for x, so we need to isolate it. To do this, we divide both sides of the equation by 0.15:
x = 60/0.15 = 400
So, 60 is 15% of the number 400.
