Estimate: 7 Exact: 8.45

Work Step by Step

We need to divide: $0.8\overline{)6.76}$ First, we estimate by rounding: $~~~7$ $1\overline{)7}$ Next, we find the exact answer. We move the decimal place once to the right to simplify the division: $~~~~~8.45$ $8\overline{)67.60}$ $~~~\underline{64}$ $~~~~~~36$ $~~~~~~\underline{32}$ $~~~~~~~~40$ $~~~~~~~~\underline{40}$ $~~~~~~~~~~0$ We see that our estimate and exact answers are a bit off from each other.
