Question

Quizplus · Accepted Answer

To estimate the quotient, we round the divisor to the nearest 10, which is 8310, and the dividend to the nearest hundred-thousand, which is 110,000,000. Then, we divide:
$$\frac{110000000}{8310} \approx 13229$$
Out of the given answer choices, only option D has a quotient that is closest to our estimate.
