Questions & Step-by-Step Solutions
If 60% of students in a school are girls and 40% of the girls play basketball, what percentage of the total students are girls who play basketball?
Step 1: Understand that 60% of the students in the school are girls.
Step 2: Understand that 40% of the girls play basketball.
Step 3: To find the percentage of total students who are girls that play basketball, first convert the percentages to decimals: 60% becomes 0.6 and 40% becomes 0.4.
Step 4: Multiply the decimal for girls (0.6) by the decimal for girls who play basketball (0.4): 0.6 * 0.4.
Step 5: Calculate the result of the multiplication: 0.6 * 0.4 = 0.24.
Step 6: Convert the decimal back to a percentage: 0.24 becomes 24%.
Step 7: Conclude that 24% of the total students are girls who play basketball.
