Question
The sum of 440 and 560 using front – end estimation is ______.
400
1000
700
900
Hint:
We have to find the sum of 440 and 560 using front end estimation. In front end estimation firstly we will round off the numbers i.e. 440 and 560. The number obtained after rounding off will be added to get the required number.
The correct answer is: 1000
Rounding the number 440 =400 Rounding the number 560= 600 Sum of 400 and 600 = 400+600 =1000 So, the sum of 440 and 560 using front end estimation is 1000.
