Question

Three-fourths of the sixth grade students at Ashlee’s school are twelve years old. One-half of the twelve year old students are boys. What fraction of the sixth grade students are twelve year old boys?

Answer 1

Answer:

3/8

Step-by-step explanation:

The easiest way to do this is by assuming a number for the total number of students. Let's say there are 24 kids total. 3/4 of that is 18, which is the number of 12 year olds. Half of this number is 9, so that is the number of boys. Now we have to find what fraction 9 is out of 24. 9/24 simplifies to 3/8.
