Let's solve the rounding decimal problems step by step.

Part 1: Round each number to the nearest hundredth.

To round to the nearest hundredth, we look at the thousandths place (the third digit after the decimal).
- If it is 5 or greater, we round up the hundredths place.
- If it is less than 5, we keep the hundredths place as is.
