Comparing and Ordering Numbers
Comparing numbers is the process to identify if a number is greater or lesser or equal to another number.
Following are the symbols used for comparing numbers:
- The number 15 is greater than 9. We can write it as: 15 > 9.
- The number 21 is less than 32. We can write it as: 21 < 32.
- The number 40 is equal to 40. We can write it as: 40 = 40.
Steps to Compare Numbers
Step 1: Count the number of digits.
Step 2: If the number of digits is different, the number with more digits is greater than the number with fewer digits.
Step 3: If the number of digits is the same, start comparing the digits from the extreme left till you get the unequal digits.
Question 1: Compare the numbers 23,567 and 23,786.
Step 1: the numbers have 5 digits. On comparing the digits from the extreme left it is observed that the first unequal digit is at hundreds place.
Step 2: The number 23,567 has 5 at hundreds place and 23,786 has 7 at hundreds place. Since 7 is greater than 5, the number 23,786 is greater than 23,567. Hence, the correct answer is 23,567 < 23,786.
Question 2: Compare the numbers 54,684 and 4684.
Answer: The number 54,684 has 5 digits, and 4684 has 4 digits. We know that the number with more digits is bigger. Therefore, the correct answer is 54,684 > 4684.
Ordering numbers means arranging the numbers in a specific order.
The numbers can be arranged in ascending order and descending order.
Ascending order: order means arranging the given numbers from smaller to bigger.
- 2403, 2419, 2455
- 54907, 60000, 61578
- 5048, 56980, 70750
Descending order: order means arranging the given numbers from bigger to smaller.
- 2455, 2419, 2403
- 61577, 60000, 54907
- 70750, 56980, 5048
