3.305
+1.7
5.005
Line up the decimal points and add like you usually would add.
5.005 is the answer.
Well I don't know. Let's figure it out together.
You said (a number) divided by 12 gives you 9 .
A fraction is the easiest way to show division, so
you can write this equation:
(number) / 12 = 9
Now you can multiply each side of the equation by 12 .
When you do that, you have ...
number = 9 x 12
<em>number = 108</em> .
Now you know how to find it. That's even better than just
having the answer.
5/12, change the denominator to 12 cuz it has to be common
