Hi All,

I'm trying to multiply the below..

so this would symplify to

leaving

But the answer is n = 3/10. So where did I go wrong?

.. How....?

Thanks,

Hi dumluck,

Simplifythe equality. Both sides.Then cross multiply.You will then get the right answer

Hello, dumluck!

As bjhopper suggested, reduce the fractions first.

Thanks Soroban,

In the above where you have seperated the symplification into three fractions (i.e you could put a line between the fractions and symplify each seperately); Is that the typical first step? As in, take each fraction and try to find a divisor, if there are no divisors look at the whole (as you have done with the '25' for the fraction on the right?). The concept I grasp, it seems to be the analysis of the problem I'm not grasping. - Jan 12th 2011, 08:08 AMHallsofIvy

Hi again dumluck,

You are making mistakes in simplifing.Left side simplifies to 250/3.Right side to 25/n.
