The answer is 19.4047.

To find the answer, follow my instructions:

First, find the difference or subtract 21.23 and 2.04. You’ll get 19.19.

Second, find the sum or add the numbers 1.115, 3.18, 22.0613, and 12.2384. Remember that when adding numbers that are decimals, you have to align all of the decimal points to get the right answer. The sum of all those numbers are 38.5947.

Third, gather your data. So you got the numbers 19.19, and 38.5947. The question is asking for the difference between them. Remember that difference means subtraction or subtracting/minus. So subtract those numbers. You’ll get 19.4047.
