Answer:
To estimate the quotient of 228 divided by 19 using compatible numbers, we can round both numbers to the nearest compatible numbers and perform the division.
Compatible numbers are numbers that are easy to work with mentally and can be used to estimate calculations. In this case, we can round 228 to 230 and 19 to 20, as they are compatible numbers.
Let's calculate the estimate using these rounded numbers:
Estimate: 230 divided by 20
230 divided by 20 is equal to 11.5
Therefore, using compatible numbers, the estimate for 228 divided by 19 is approximately 11.5.
