The ratio of the number of boys to girls is 5: 7 if there are 600 studens in school how many girls are there

There would be 350 girls in the school.

Step-by-step explanation:

We can find this by creating two proportions. the first fraction would be the number of girls out in the sample:

7/12

The second part would be the amount of girls in the whole school. We can set the girls as x since we do not know.

x/600

Now we can set the two equal to each other and cross multiply.

7/12 = x/600

600*7 = 12*x

4200 = 12x

350 = x

y=1/4x-4
