Explanation:
We need to round each number off to two decimal places.
When the digit of the last decimal place of a number is
If the digit is less than
8.43, 0.01, 15.24, 39.92
Explanation:
Rounding is a way of simplifying numbers. To round to a given place value, the next digit in the number is checked; if that number is four or less, the number "rounds down," or stays as is. If the number is five or above, the number "rounds up"; that is, the place value of interest increases by one.
Rounding the decimals to two decimal places means checking the digit that is three places after the decimal.
In the first example, 8.432, the digit 2 is 4 or less, and therefore the number of interest (i.e. two decimal places) rounds down and stays as 8.43.
In the second situation, 0.005, the digit 5 is five or above, and therefore the number of interest rounds up. Thus, 0.01.
In the third given situation, 15.243, the third digit is 3, and therefore rounds down. The result, then, is 15.24.
Finally, the "8" in 39.918 rounds up, resulting in 39.92.
