To solve the problem of rounding each decimal to the nearest hundredth, we need to follow these steps:
Steps for Rounding to the Nearest Hundredth:
1. Identify the hundredths place (the second digit after the decimal point).
2. Look at the digit in the thousandths place (the third digit after the decimal point).
- If the thousandths digit is
5 or greater, round up the hundredths digit by 1.
- If the thousandths digit is
less than 5, keep the hundredths digit as it is.
3. Drop all digits after the hundredths place.
Let's apply this step-by-step to each number in the table.
