OpenStudy (k_lynn):

First you're going to want to find out how many girls there are. You can do that by subtracting \[30-14\]What do you get when you subtract?

OpenStudy (anonymous):

16

OpenStudy (k_lynn):

yep, and they want the ratio boys TO girls. That means that the amount of boys goes first. \[\frac{ Boys }{ Girls }\] Put in the amount of boys on top and the amount of girls on the bottom. what do you get?

OpenStudy (anonymous):

so d is right?

OpenStudy (anonymous):

yes

OpenStudy (k_lynn):

No, not quite. Remember that the amount of boys go on top.

OpenStudy (k_lynn):

There were 14 boys and 16 girls. 14 goes on top and 16 goes on the bottom \[\frac{ 14 }{ 16 }\]What number goes into 14 and 16? They're both even numbers. That should give you a hint.
