Answer: 21 of the finalists were boys. Explanation: We are trying to figure out what 25% of 28 is. We can convert 25% into a fraction. 25%= 1/4 and 28= 28/1 Multiply and you’ll get: 28/4 which equals 7. So 25% of 28 is 7. With the remaining step, you subtract 7 from 28 to get the amount of boys in the final because 7 is the amount of girls. 28 finalists- 7 girls = 21 boys
