In this case:
Tenths place: the 9 closest to the decimal point
Hundredths place: the second nine after the decimal point
Tens place: 4
Hundreds place: 1
Let's start with the tenths place. To figure out whether we round up or down, we look at the number after the place we are rounding. In this case, it is a 9. If the number is below five, then the place stays the same. If it is five and up, then the place rounds up. 9 is above 5, so this rounds up to 142.0.
So, you would do the same thing with the other places.
Tenths: 142.0
Hundredths: 142.00
Tens: 140
Hundreds: 100
Hope this helps.
