fifteen out of 25 students in Mrs. Smith's class are boys. what is the ratio of boys to girls?
i put 1 to 6. is that right?

Nope.
25  15 = 10
15/10 = 3 to 2 
There are 15 boys. Out of 25 students, that means there are 10 girls. Reduce 15/10 for your answer.

15/25= 2515= 10 girls
> 10:15
15/25= 2510= 15 boys
10 divided by 5 = 2
15 divided by 5 = 3
the answer is 2:3
I think... 
No, Raluca, it's 3:2.

The problem states that there are more boys to girls. The student is to find the ratio of BOYS to GIRLS.
Raluca got it backwards. There are 3 boys for every 2 girls.
