Answer:
Let's round.
The hundredths place is the place two place values to the right from the ones place.
3 . 1 4 2
ones tenths hundredths thousandths
The four is in the hundredths place.
To round, look to the next smaller place value.
It's the thousandths!
In the thousandths, there are 2 thousandths.
If the number is greater than 4, you should make the hundredths place 1 bigger.
If, however, the number is less than 4, you should keep the number the same.
2 is not greater than 4, but it is less.
So, 3.142 rounded to the nearest hundredth is 3.14.
