Final answer:
To subtract 2100 from 5 and write the answer as a mixed number, we subtract the ones place, tens place, and hundreds place separately. The simplified answer is -2 5/1.
Step-by-step explanation:
To subtract 2100 from 5, we subtract the ones place, tens place, and hundreds place separately. We start with the ones place, which gives us 5 - 0 = 5. Then we move on to the tens place, which gives us 0 - 0 = 0. Finally, we subtract the hundreds place, which gives us 0 - 2 = -2. Since we have a negative result, we can convert it to a mixed number by writing it as -2/1. Therefore, the simplified answer written as a mixed number is -2 5/1.
