Question

The ratio of boys to girls in a class is 2:3. There are 30 students in the class. How many students are boys?

Answer 1

12 students are boys

Explanation:

2+ 3 = 5

30/5 = 6

So there are 6 groups of 2 boys and 6 groups of 3 girls

2 x 6= 12

6× 3 = 18

Now we can check our answers by adding 12 and 18

12 + 18 = 30

Looks like it adds up to 30 so 12 students are boys
