Can you please elaborate how to simply this.

**Quote:**

% greater =\(k * sqrt(0.8) - k * sqrt(0.2)/k * sqrt(0.2) * 100\)

Here I go:

\(sqrt(0.8)\) = sqrt(8)/sqrt(10) = [2*sqrt(2)]/sqrt(10)

\(sqrt(0.2)\) = sqrt(2)/sqrt(10)

You know we can cancel 'k' from denominator and numerator.

Similarly, you have sqrt(10) both at numerator and denominator, so you can cancel that out.

Therefore, you are left with [2*sqrt(2) - sqrt(2) ] / sqrt(2) ] *100 = [sqrt(2) ] / sqrt(2)] *100 = 100%

Does that make sense?

Took a while to realize this but finally got it. Yes it makes perfect sense.
