Answer:
Using compatible numbers the estimate quotient is 26.
Explanation:
Given : Quotient,

To find : Use compatible numbers to estimate the quotient ?
Solution :
Compatible numbers are pairs of numbers that are easy to add, subtract, multiply, or divide mentally.
When using estimation to approximate a calculation, replace actual numbers with compatible numbers.
Now,

Using Compatible numbers,
Estimate 776 as 780
Estimate 28 as 30.
So,

Therefore, Using compatible numbers the estimate quotient is 26.
