There are 22 girls and 55 boys in Fortnite Club.

Step-by-step explanation:

If we add 2+5 it's equal to 7. So we have to make 7 parts of members in the club. That is 77 so we just devide 77 over 7 and get 11. So now we know 1 ratio will be equal to 11. so we multiply 2 by 11 or 2*11=22. So we have 22 girls. And the ratio of boys are 5 so 5*11=55. So there's 55 boys.

To Check the solution we should add 55+22=77. That's the total number members in the Club including boys and girls.
