Question

The difference of 587 and 222 using front -end estimation is ________. 

  1. 200
  2. 300
  3. 400
  4. 500

hintHint:

We have to find the difference of 587 and 222 using front end estimation. Firstly we will round off both number to nearest highest number place, in this question we will round off to nearest hundred. Further we will subtract the numbers and will get the required number i.e. the estimated difference of 587 and 222.

The correct answer is: 400


Rounding off 587 = 600
Rounding off 222= 200
difference between these numbers
=600-200
=400
So, the difference of 587 and 222 using front end estimation is 400.

Estimate the sum of 5786 and 2126 to the nearest thousands. 

Step 1 : Round Off ;
if last three digits are more than or equal to 500 round off to nearest thousand greater than number.
5786 rounds off to 6000.
if last three digits less than 500, then round off to nearest thousand smaller than number.
2126 rounds off to 2000.
Step 2 : Perform Addition
6000 + 2000 = 8000 ;
So , 8000 is our estimated sum .

Estimate the sum of 5786 and 2126 to the nearest thousands.

Estimate the difference between 7123 and 3678 to the nearest thousands. 

Step 1 : Round off
If last 3 digits are less than 500 than round off to nearest 1000 less than the number .
so, 7123 rounds off to 7000 .
If last 3 digits are  greater than or equal to 500 than round off to nearest 1000 greater than the number.
so, 3678 rounds off to 4000 .
Step 2 : On performing subtraction
7000 - 4000 = 3000 ;
So, 3000 is our estimated answer.

Estimate the difference between 7123 and 3678 to the nearest thousands.
