    88

    Step-by-step explanation:

    Let's see - if there are 3/5 girls, there must be 2/5 boys. Assuming everyone in the class is binary, of course.

    So 2/5 of 220 is the number of boys. When you see "of," always think multiplication!

    2/5 of 220

    2/5 * 220 = 88 boys in 7th grade
