ilovecake · Answer

So I do 18 divided by 7 which is 2

ilovecake · Answer

Is that right?

anonymous · Answer

That's not right.  
$$\frac{ 18 }{ a }=7$$
First you need to clear the fraction.  So multiply both sides by a.
That gives you:
18 = 7a
Can you solve that for a?  One more step.

I think the answer would be D?

anonymous · Answer

No.  If you have 18 = 7a, you divide by the number in front of the variable.  So you'd divide both sides by 7...
