Well's College in New York was previously an all girls school. In 2005, the college began to allow boys to enroll. By 2012, the ratio of boys to girls was 3:7. If there were 200 more girls than boys, how many boys were enrolled that year?

150 boys

Step-by-step explanation:

Let the number of boys be x

Since there were 200 more girls than boys, the number of girls will be: = x + 200

Since the ratio of boys to girls was 3:7, this can be solved further below:

3/7 = x/x+200

Cross multiply

(7 × x) = 3(x + 200)

7x = 3x + 600

7x - 3x = 600

4x = 600

x = 600/4

x = 150

The number of boys enrolled is 150

Number of Girls will be:

= X + 200

= 150 + 200

= 350

Check: Number of boys / Number of girls

= 150/350

= 3/7

= 3:7

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
