Answer 1

The concept being tested is the rounding of numbers. While it's true that for simple rounding purposes if a digit is less than 5 one would round down, the division of 0.0184 by 2 (0.0092) does not necessitate any rounding unless further instructed by context.

Step-by-step explanation:

The question is asking whether to round down the number 0.0184 when dividing by 2 because the number after the decimal to be dropped is less than 5. According to the standard rounding rules, when the digit you are dropping is less than 5, you do round down. However, in the context of the original question where it's just dividing 0.0184 by 2, there's no need to round at all, and you would simply compute the division. The provided examples illustrate how rounding works:

• 0.028675 rounds "up" to 0.0287 as the dropped digit is greater than 5.
• 18.3384 rounds "down" to 18.3 as the dropped digit is less than 5.
• 6.8752 rounds "up" to 6.88 as the dropped digit is 5, and a nonzero digit follows it.
• 92.85 rounds "down" to 92.8 as the dropped digit is 5, and the retained digit is even.

However, when dividing 0.0184 by 2, you actually get 0.0092 without any need for rounding.
