The student population of a school consist of 300 girls and 500 boys. If 53% of the girls play sports, and 39% of the boys play

Ymorist [56]

Hello!

Convert the percentages to decimals by dividing them by 100, and then multiply them by the amount of boys and girls.

53 ÷ 100 = 0.53 as a decimal

0.53 × 300 girls = 159

This means that 159 of the 300 girls play sports.

Repeat this to calculate how many boys play sports.

39 ÷ 100 = 0.39

0.39 × 500 = 195

This means that 195 out of the 500 boys play sports.

Final Answer:

More boys play sports than girls.
