and 203214702

Comparing and Arranging the Numbers

In earlier classes, we learnt to compare the small numbers. We follow the

same rules for comparing the large numbers.

Case I. The numbers having different numbers of digits

The number having more digits is greater than the number having

less digits.

Examples: 246730 > 99987

(6 digits) (5 digits)

57695008 < 100000000

(8 digits) (9 digits)

Case II. The numbers having the same number of digits

If the number of digits in both the numbers is the same, start

comparing the digits from the highest (leftmost) place and continue

till two different digits are found. Compare these digits to decide
which number is greater or smaller.

Examples: 4567328 < 4592576 [ 6 < 9]

2975641 > 2975609 [ 4 > 0]

Example 18: Choose the greatest number in the following. 456872943,
456827943, 456827493. Also, arrange the numbers in

ascending order.

Solution: Here, all the numbers have equal number of digits.
Therefore, to find out the greatest number in them, we

put the digits in the place-value chart.
