Question 554725: If 1/9 of the girls were older than 10 years old and 1/6 were younger than 10 years old, what fraction of the girls were ten years old?
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
1/9+1/6 = 2/18+3/18 = 5/18

So 5/18 of the girls are NOT 10 yrs old.

This means that 1 - 5/18 = 18/18 - 5/18 = 13/18 of the girls are 10 years old.
