My answer. I'm not sure how to do this.

I know that there are 3/8 males.-------------------------------------------------------------------------------------------------------

In the book they did:

For girls,

**3/10***

**5/8**=

**3/16**girls (why they multiplied both fractions?)

For boys,

**1/3***

**3/8**=

**1/8**boys (same, why they multiplied both fractions?)

Then they subtracted

**3/16**-

**1/8**to find the audience. So there is 1/16 audiences. (why subtract both fractions?)

Lastly, they did

**1/16**= 21. So they got an another of 336. (why did they equal it to 21?)

I'm not sure how the book did it.

Is there an easy way to do this creating an algebraic expression?
