There must be three decimal places in the answer:
#267.267#

Explanation:

The issue here is probably the number of decimal places in the answer.

Multiply the numbers, ignoring the decimal point.

#14.3*2.1*8.9#

#143*21*89#

#3003*89#

#267 267#

This will give the number: #267 267#

Count the number of decimal places - there are three.
There must be the same number in the answer.

Hence #267.267#
