A brownie has 480 calories in total, and 240 calories come from fat. What percent of the total calories comes from fat?

1. Divide the part by the whole: 240 divided by 480. 2. This gives 0.5. 3. Move the decimal point two places to the right and add a percent sign: 50%. 4. So 50% of the calories in the brownie come from fat. _Source: OpenStax Prealgebra (CC BY 4.0), Ch 6 "Percents", section 6.2 Solve General Applications of Percent_
