Hi.
I am really struggling to find a way to work out how to do percentages, via pencil and paper. Is there a simple way/method for me to use that I could apply to the following problem:-
25% of £4.99
Your help is much appreciated.

hi
here's a Trick
if you wanna find the $\displaystyle 21 \%$ of $\displaystyle 4.99$ :
you know that $\displaystyle 21$ $\displaystyle \%$ $\displaystyle = 10 \% + 10 \%+ 1 \%$
$\displaystyle 10 \%$ of $\displaystyle 4.99$ is equal to $\displaystyle 0.499$.
$\displaystyle 1 \%$ of $\displaystyle 4.99$ is equal to $\displaystyle 0.0499$.
so $\displaystyle 21 \% $of $\displaystyle 4.99$ is equal $\displaystyle 0.499+0.499+0.0499 = 1.0479$.
