A school has 500 students. 60% of them are girls. How many boys are there?

Step 1 ：Convert the percentage of girls to a decimal: \(60\% = 0.60\)

Step 2 ：Calculate the number of girls: \(500 \times 0.60 = 300\) girls

Step 3 ：Subtract the number of girls from the total number of students to find the number of boys: \(500 - 300 = 200\) boys
