1/3 of students at a school are boys. If there are 600 students at the school, how many are girls?

1/3 of students at a school are boys. If there are 600 students at the school, how many are girls?

If 1/3 are boys, then the number of boys is:
600 * 1/3
600/3

We type this fraction into our search engine to simplify, and we get:
200

Now we need to find how many girls are at the school:
Girls = Total Students - Boys
Girls = 600 - 200
Girls = 400
