I think that we MUST take the "apples" and "oranges" approach.

Otherwise, what is the balance in the "fruit basket"?

Receive $3/64
Receive $0.02
Spend $1/64

What is the balance?

It's value is a little more than $3/64
and a little more than $0.05

But we must be exact.
The balance is exactly $0.02 + $2/64 which we might print as $0.02 + $1/32

It is also of the same exact value as $0.05125
But those are "bananas".
