Final answer:
To estimate the value of a limit to five decimal places, round the calculated result to the nearest fifth decimal place.
Step-by-step explanation:
In calculations involving multiplication and division, limit significant figures to the least number of significant figures in all the data values. For example, if we are dividing 23 by 448, which have two and three significant figures respectively, we should limit the final reported answer to two significant figures (the lesser of two and three significant figures).
To estimate the value of a limit to five decimal places, you can round the calculated result to the nearest fifth decimal place. If the digit immediately following the fifth decimal place is greater than or equal to 5, round up. Otherwise, leave the fifth decimal place as it is. This will give you an estimated value of the limit to five decimal places.
For example, if the calculated result is 2,085.5688 and you want to estimate it to five decimal places, you would round it to 2,085.6 because the digit in the sixth decimal place (8) is greater than 5.
