To compare decimals, you can follow these steps:

Step 1: Compare the whole number part of the decimals. In this case, the whole number parts are both 0, so they are equal in this aspect.

Step 2: If the whole number parts are equal, compare the decimal parts. In this case, the decimal part of 0.40 is 40, and the decimal part of 0.04 is 4.

Step 3: Since the decimal part of 0.40 is greater than the decimal part of 0.04, you can conclude that 0.40 is greater than 0.04.

Therefore, the comparison is: 0.40 > 0.04.
