Final answer:
To estimate the quotient 2116 ÷ 7 using compatible numbers, round 2116 to the nearest multiple of 7, which is 210. Divide 210 by 7 to get the estimated quotient of 30.
Step-by-step explanation:
To estimate the quotient 2116 ÷ 7 using compatible numbers, we can round 2116 to the nearest multiple of 7, which is 210. Then, we can do the division 210 ÷ 7 to get the estimated quotient. Since 210 is divisible evenly by 7, the quotient is 30. Therefore, the estimated quotient of 2116 ÷ 7 is 30.
