### Theory:

General rule for comparing decimals:
Step 1: First compare the highest place values of whole parts of two decimal numbers.

Step 2: If the highest place values of two decimals are the same, then compare the second-highest place of digits.

Step 3: If the whole part is the same, then compare the decimal part of tenth place.

Step 4: If it is also same, then compare the decimal part of the hundredth place. The same procedure can be extended to any number of decimal digits.
Example:
1. Compare $$67.62$$ and $$33.41$$.

Here, the highest place value is tens place, which is different in both the numbers.

$$6$$ $$>$$ $$3$$

Therefore, $$67.62$$ $$>$$ $$33.41$$.

2. Compare $$56.75$$ and $$56.77$$.

Step 1: Here, the whole part $$56$$ is same in both the numbers.

So, compare the tenth place.

Step 2: Tenth place of both numbers are $$7$$ and $$7$$. They are also same.

So, compare the hundredth place.

Step 3: Hundredth place of both numbers are $$5$$ and $$7$$. Here, $$5 < 7$$.

Therefore, $$56.75 < 56.77$$.
Adding zeros at the right end of decimal digits do not change the value of that decimal number.
1. $$25.1 = 25.10$$

2. $$621.035 = 621.0350$$
