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.

$14.3 \cdot 2.1 \cdot 8.9$

$143 \cdot 21 \cdot 89$

$3003 \cdot 89$

$267 267$

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 $267.267$
