There are 2 girls and 6 boys playing a game. How many additional girls must join the game so that 5/8 of the players are girls?

since there are 2 girls and 6 boys the ratio right now is 1/3 and to solve the number of girls we subtract 5 from 8 to get 3 we then do 6/3 to get 2 and that means it has to be 2 times so the number of girls must be 10 and we want how much we add so we get 10-2=8.Now we get that we need to add 8 more girls

[2 + x] / [8 + x] = 5/8, solve for x

Cross multiply

[2 +x] =5 + 0.625x

0.375x  = 3 Divide both sides by 0.375

x = 8 new girls.
