To round a number to two decimal places, follow these steps:

1. Identify the third decimal place. This is the digit immediately after the second decimal place.
2. If the third decimal place is 5 or higher, round up the second decimal place by increasing it by one. If it is 4 or lower, simply keep the second decimal place as it is.
3. Ignore or remove all digits after the second decimal place.

Using these steps, let's check your answers:
