5.25 (rounded)

322×163, however = 52,500 (rounded)

To find out the where the decimal place belongs, simply count the number of digits behind the decimal.

Ex: 3.22 and 1.63 together both have 4 digits behind the decimal. So you take that and start at the end of the answer you got and move the decimal to the left 4 places.

1: 5250.0

2: 525.

3:52.5

4: 5.25Explanation:
