Final answer:
The sum of the numbers 811, 901, 88, and 5 is 1805, which is found by adding the hundreds, tens, and units place values separately and then combining them.
Step-by-step explanation:
To find the sum of the numbers 811, 901, 88, and 5, we simply add them together:
- Add the hundreds place: 800 + 900 = 1700
- Add the tens place: 10 + 80 = 90
- Add the units place: 1 + 1 + 8 + 5 = 15
- Combine the sums: 1700 + 90 + 15 = 1805
Therefore, the sum of the numbers is 1805, which corresponds to answer choice a.
