Remember that a place value can be defined as the value represented by a digit in a number based on its position in the number. With decimal numbers, we can have a guide from the decimal point, and with natural numbers, we have a guide from the comma.
So, if we look at the numbers on the exercise we note that
- 3s in 43,862 is placed first before the comma indicating that their place is in the thousands.
- 3s in 75,398 is placed first after the comma indicating that its place is in the hundred.
