Final answer:
The request is for 5 numbers with 8 in the ones place, which can be any numbers ending in 8 such as 18, 28, 38, etc. The concept of significant figures mentioned does not directly apply to creating these numbers, as they are simply constructed by having 8 in the ones place without additional rounding considerations.
Step-by-step explanation:
The question is asking for 5 numbers with 8 in the ones place. To construct such numbers, you can choose any digit for the tens, hundreds, and so on, but the ones place must be an 8. For example, 18, 28, and 38 all have 8 in the ones place. The process of determining significant figures occurs in rounding and measurement calculations, where each digit in a number has a potential significance based on its position and the convention followed.
In the context of rounding:
- If the first dropped digit is 5 or greater, the previous digit is rounded up.
- If the first dropped digit is less than 5, the previous digit is kept the same (rounded down).
Applying this to creating numbers with an 8 in the ones place is straightforward, as the 8 is already the final digit and requires no rounding.
