Answer: -130.

Step-by-step explanation: To round −74.41 to the nearest whole number, we look at the tens place, which is the digit 4 in the number −74.41. Since 4 is less than 5, we round down to the previous whole number, which is −74.

To round 55.816 to the nearest whole number, we look at the tens place, which is the digit 8 in the number 55.816. Since 8 is greater than or equal to 5, we round up to the next whole number, which is 56.

Now that we have rounded both numbers to the nearest whole number, we can easily subtract them to get an approximate answer:

-74 - 56 = -130

Therefore, an approximate solution to −74.41- 55.816 is -130.
