Answer :
Final answer:
Approximations simplify calculations by rounding up or down to the nearest whole number. We can estimate A) 10.5 as 11, B) 0.5 as 1, C) 10.1 as 10, and D) 0.4 as 0.
Explanation:
In the field of mathematics, approximate values are essentially used as a means to simplify calculations. In this context, we're looking to estimate the values of A) 10.5, B) 0.5, C) 10.1, and D) 0.4. By rounding to the nearest whole number, we can estimate A) 10.5 as 11, B) 0.5 as 1, C) 10.1 as 10, and D) 0.4 as 0.
Let's take A) 10.5 as an example. As per the rules of approximation, you would round up if the decimal is 0.5 or more, and round down if it's less. In this case, since we're approximating 10.5, we're rounding up to 11. The same rules apply to the rest of the numbers.
