Final answer:
We must examine the farthest-right significant figure of 11..77.99 in order to determine its final digit. It is in the hundredths place in this instance. The last digit of 11..77.99 is 8.
Step-by-step explanation:
The last digit of 12.16 is 2 because it is in the tenths place.
The last digit of 7.9.3 is 9 because it is in the ones place.
To find the last digit of 11..77.99, we need to look at its farthest-right significant figure. In this case, it is in the hundredths place.
Because the first digit to be dropped (in the thousandths place) is greater than 5, we round up to get a final answer of 11..78.
"Last digit calculation" typically refers to the process of determining or finding the final digit of a numerical value, especially in the context of mathematical operations or numerical representations.
