Then why don't we divide everything by 2 in this case and then multiply by a? In this case we could remove the a from the () and write 2 x a, but it still has to be done separately from the rest of the problem. So how can we be sure that the (9+3) is not part of the denominator if written on one line? |
Here is the equation for the answer 2:
48/[2(9+3)]
This makes the denominator 24 so when you do this above equation, you would get two. BUT...the question posted did not have the brackets, you guys can't make them up.
