Answer: 2.99
Explanation: In this problem, we're asked to round 2.9857 to the nearest hundredth. The hundredths place is located two places to the right of the decimal point so the digit in the rounding place is the 8.
Next, look at the digit to the right of the rounding place.
Since the digit to the right of the rounding place, 5, is greater than or equal to 5, we round up.
This means that we add 1 to the digit in the rounding place so 8 becomes 9 and we change all digits to the right
of the rounding place to 0.
So 2.9857 rounded to the nearest hundredth is 2.9900.
Finally, remember that when rounding decimals, we can drop and zeroes to the right of the decimal point that are also to the right of the rounding place.
So our final answer 2.99.
