Final answer:
To change a fraction to a percent using proportions, set up a proportion where the fraction is equal to x/100. Solve the proportion to find the percent.
Step-by-step explanation:
To change a fraction to a percent using proportions, you can set up a proportion where the fraction is equal to x/100. In this case, we have 12/100. Setting up and solving the proportion, we get:
12/100 = x/100
Cross multiplying, we have 100 * 12 = 100 * x
1200 = 100x
Dividing both sides by 100, we get x = 12.
So, 12/100 is equal to 12%.
