Choose the "incorrect" digit in the estimate.

• A. 3
• B. 9
• C. 0
• D. All the digits are correct.

Answer 1

The correct option is A 3


From the above number line, we can observe that the nearest tenths place value of 2.911 is 2.9

But, 2.9 can also be written as 2.90

Now, comparing 2.90 with 3.90, we find that the incorrect digit in the estimate is 3.

∴ The incorrect digit in the estimation is 3.
