Find the missing number.
5/15 = ?/3
Is 1 the correct answer?

5 / 15 = x / 3
5 * 3 = x * 15
15 = 15 x Divide both sides with 15
x = 1
5 / 15 = 1 / 3 
I got the answer 1 by doing this...
15 divided by 3 = 5
5 divided by 5 = 1
Is that a wrong way to answer the problem?
That's the way my book shows. 
That's the way I got the answer too. Thank you!!!
