Final answer:
To estimate the quotient, round the given numbers and perform the calculations. The quotient is 2.
Step-by-step explanation:
To estimate the quotient using compatible numbers, we will round the given numbers to numbers that are easier to work with. For example, we can round 8 and 6 to 10 and 5, respectively. Similarly, we can round 1 and 7 to 0 and 10. So, the problem becomes 10/5 ÷ 0/10. Dividing 10 by 5 gives us 2, and dividing 0 by 10 gives us 0. Therefore, the quotient is 2.
