What is the difference of the place values of the two 8s in the number 2853847 ?

  • A.799200
  • B.792000
  • C.799920
  • D.7999200

Answer: A

The difference is 799200.

In 2853847, the first 8 is in the hundred-thousands place and the second 8 is in the hundreds place:

\[ \begin{aligned} \text{place values} &= 800000 \text{ and } 800 \\ 800000 - 800 &= 799200 \end{aligned} \]

The face value of each 8 is the same, but place value depends on position. 792000 and 799920 come from placing the second 8 in the thousands or tens place, and 7999200 adds a digit.
