Answer 2

Given: Two numbers 3126 and 1029

To find: estimation of the difference of 3126 and 1029 to the nearest 100

Solution:

While estimating or rounding off any number to its nearest 100,

• First, check the tens place of the number
• If the digit at the tens place is less than 5, then all the succeeding digits including the digit at the tens place will become 0 (zero), with no change in the digit at the hundreds place
• Otherwise, if the digit at the tens place is equal to or more than 5, then all the succeeding digits including the digit at the tens place will become 0 (zero), with the addition of 1 in the digit at the hundreds place.

Computing the difference,

3126 - 1029 = 2097

Th  H   T  O

2   0   9   7

Now, the digit at the tens place in the number 2097 is 9.

As, 9 > 5,

Therefore, adding one to the digit at hundreds place (i.e. 0) and making all succeeding digits 0,

the estimated number will be,  2100.

Thus the estimation of the difference of 3126 and 1029 to the nearest 100 is 2100
