Comparing Numbers:
In comparison of numbers we will learn to compare 4-digit numbers. The same rules are applied to compare numbers having more than 4 digits.
To learn and understand comparison of numbers the rules are generalized here:
Different Number of Digits
If two numbers which are to be compared do not have same number of digits, the number with more number of digits is greater.
(i) The number of 2 digits is greater than the number of one digit.
(ii) The number of 3 digits is greater than the number having 2 or 1 digit.
(iii) The number of 4 digits is greater than 3 or 2 or 1 digit number.
(iv) 5-digit number > 4-digit number > 3-digit number ………… etc.
(v) 6-digit number > 5-digit number > 4-digit number ………… etc. As: 10 > 9,
100 > 99 > 9,
239 > 98, 1250 > 998,
23051 > 8735
351246 > 92835 > 5298 > 376 > 93.
Same Number of Digits
(a) If two numbers have the same number of digits, we compare them on the basis of the first digit from the left. The number with the greater extreme left digit is greater.
In 634 and 336 the digits at the left in 634 is 6 and in 336 is 3
Also 6 > 3
