Answer: 2.9
=========================================================
Step-by-step explanation:
Let's underline the digit in the hundredths place
The 9 is underlined. It's the place value two spots to the right of the decimal point.
The next digit to the right is 6. This is five or larger, so we'll bump the 89 up to 90
Therefore, we go from 2.89 to 2.90 or simply 2.9
Everything else to the right of the hundredths digit is erased.
