Answer:
Max's estimate of the difference is 400.
Step-by-step explanation:
Given : Max estimates 718 - 331 by rounding each number to the nearest 100.
To find : What is Max's estimate of the difference?
Solution :
Rounding each number to the nearest 100 means
1) If the tens place value is greater than or equal to 5 then the hundred place round by 1.
2) If the tens place value is less than 5 then the hundred place remain same.
Now, Estimate 718 by rounding number to nearest 100 is 700.
Estimate 331 by rounding number to nearest 100 is 300.
The difference of their estimation is 700-300=400.
Therefore, Max's estimate of the difference is 400.
