It doesn't work because an instance of the Decimal object can't be used for
mathematical calculations (such as division and multiplication) with floats or

AFAIK decimals can be divided and multiplied with integers just fine.
They throw an "unsupported operand" error when mixed with floats.
The operations should just work, at least this do:
""""""
In [3]: from decimal import Decimal
In [4]: a=Decimal(str("1.1")) + Decimal(str("2.3")) +
Decimal(str("57.28989"))
In [5]: a
Out[5]: Decimal('60.68989')
In [6]: print a * 25/100
------> print(a * 25
15.1724725
""""""
The error must be in another place. If I were the OP, I would print (or
use some nicer debugger) the value of all the involved variables and
check if some has an unexpected type.
