**helper**, Thursday, February 10, 2011 at 4:19pmIf you are Katherine, this question was answered in your 1st post last night.

Please check your prior post for an answer before reposting.

I pasted the answer below.

Ratio = Boys : Girls = 4 : 3

4x = number of boys

3x = number of girls

4x - 6 = 3x

x = 6

4x = number of boys = 4 * 6 = 24

3x = number of girls = 3 * 6 = 18

If another 2 girls join the choir,

18 + 2 = 20 = new number of girls

24 = number of boys

New ratio = 24 : 20 = 6 : 5
