Questions & Step-by-Step Solutions
In a pie chart representing the distribution of a school's student population, 50% are girls, 30% are boys, 15% are non-binary, and 5% are other. If there are 400 students, how many are boys?
Step 1: Understand that the total number of students is 400.
Step 2: Identify that we need to find the number of boys, which is 30% of the total.
Step 3: Convert the percentage to a decimal by dividing 30 by 100, which gives us 0.30.
Step 4: Multiply the total number of students (400) by the decimal (0.30) to find the number of boys.
Step 5: Calculate 0.30 * 400, which equals 120.
