If the ratio of boys to girls in the school is 2 to 3 how many boys are there in the school if there are 120 girls

There would be 80 boys.

Step-by-step explanation:

2 to 3 can be simplified to 1 to 1.5, if we divide 120 by 1.5 we get 80. We also know this is true because there would be 50% more girls than boys: 80*1.5=120

80 boys.

Step-by-step explanation:

So you have to get the 3 which stands for how many girl there are, and find what it is multiplied by to get 120. That will be 40. Then you do 40 times 2 because whatever you do to one side of the ratio you have to do to the other. Hope this helps.
