The ratio of girls to boys at a concert is 2:7. There are 250 more girls than boys. How many boys are there?

Asked by aidanhoyt

Answer (2)

The Girls:Boys ratio of 7:2 means that there are 7 girls for every boy. As there are 250 more girls this relates to the 7-2 part of the ratio. We can then divide 250 by 5 and multiply by 2 to get the number of boys as 100 boys

Using the ratio of girls to boys (2:7) and the information that there are 250 more girls than boys, we set up an equation and found that there are 350 boys at the concert. By solving the equation step-by-step, we were able to identify the correct number of boys based on the conditions provided. Therefore, the answer is 350 boys.
