If $x$ is the amount of old pence corresponding to 91 new pence, then

$$\frac x{240}\ =\ \frac{91}{100}$$

giving $x=0.91\times240=218.4$.

$218.4\ =\ 18\times20+2.4.$

Hence $£0.91\ \text{(decimal)}\ =\ £\mathrm{0\,\,18\,s\,\,2.4\,d}\ \text{(pre-decimal)}$.

Don't you have the problem that you don't know how many dollars there are in a dollar?EASIER if you do what we did here in Canada:

eliminate the **** penny!!

Easier if you do what we did here in Europe: only one Euro.
