Answer:
1200 and 1100
Explanation:
Tony rounded each of the numbers 1183 and 1145 to the nearest hundred.
To round the number to nearest hundred , check the digit in tens place.
If the number in tens place is greater than or equal to 5 then we add 1 in hundreds place
If the number in tens place is less than 5 then we replace the remaining digits by 0
In 1183, we have 8 in tens place so 1183 is rounded to 1200
In 1145, we have 4 in tens place so 1145 is rounded to 1100
