The table below shows the number 6275893 and the place value of each digit.
From the above each digit has the place value for example number 5 occupies the thousands, so it can be written as 5 x 1000, 3 occupies ones so it can be written 3 x 1
The process of rounding off is the same of that in decimal but the different in whole number is that we deal with place value instead of decimal place.
Round off
1. Our number that is needed for approximation is that with place value "hundreds” that is number 6. 2. As we dealt in decimal that we check the right side number after the considerable number if it is greater or less than 5 so that we can add 1 in our consideration. 3. Here the right side number is 8 and it is greater than 5 so we add 1 in our number 6 and becomes 7. 4. after completing checking and adding then all the remaining numbers in the right side of our considerable number should become 0. 5. Lastly our answer now is
