Answer: The two estimates of quotient is 522 and 523 .
Explanation:
Compatible numbers are numbers which are close in value to the given numbers, and make it easy to calculate the answer for any given arithmetic problem .
To find two estimates that the quotient is between in 1045÷2
We now that 1045 is greater than 1044 and less than 1046 i.e.1044<1045<1046
Dividing 2 from all sides ,we get
1044÷2<1045÷2<1046÷2
⇒522<1045÷2<523
As the quotient of 1045÷2 is lying between 522 and 523.
Therefore, the two estimates of quotient is 522 and 523
