Find the ratio of 18 and 30 reduced to simplest

First you'll take 18/2 which equals 9. Then 30/2 which equals 15. Then you can divide both 9 and 15 by 3. So 9/3 equals 3 and 15/3 equals 5. So the answer is 3:5.

3: 5.hahahahhaha. that's the simplest form for your question.

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2
