Good memory!
.
You were given:
.
10%2F256.21
.
In this case you need to multiply the denominator by 100 to get rid of the decimal point. But
if you multiply the denominator by 100, you must also multiply the numerator by 100. So,
you simply do this multiplication:
.

.
If you had been given:
.
10%2F2.5621%29
.
You would multiply it by 10,000 over 10,000 to get:
.
100000%2F25621
.
Hope that helps to ensure you that your memory is just as good as ever.
