Question

In a 7th grade class, the ratio of boys to girls is 3 : 2. How many boys and how many girls could be in the class? Make sure the class has 30 students or less.

Answer 1

18 boys and 12 girls make 30 students. With ratios, you can multiply the numerator and denominator by the same number and it will still be the same ratio. How I got 18 boys and 12 girls is I took 3:2 and multiplied the top and bottom by 6. Hope this helped!
