coMPARING NUMBERS

Pratham and Riya are playing a video game.

Pratham got 58 points and Ria got 69 points.
Who is the winner?

They know that 58 is on the left of 69 on the
number line. So, 58 is lesser than 69. That is, 58 < 69 or 69 > 58.
58 69

60 65 70
We can also compare numbers by following two simple rules as given below instead
of counting one by one on the number line.

Rules

1. A 2-digit number is always greater than a 1-digit numbers.
Example: 34 > 9 as 34 is a 2-digit number and 9 is 1-digit number.

2. When both the numbers are 2-digit numbers.
(a) The number that has bigger tens digit is greater.

Example: tens Ones tens Ones
4 6 3 6 Quick Check

4 > 3
So, 46 > 36 or 36 < 46. Count the number of the
given pencils and compare the two
(b) If the tens digit is the same, then numbers.
compare the ones digits. The number
that has the greater ones digit is greater.

Example: tens Ones tens Ones
5 0 5 2

5 = 5
0 < 2
So, 50 < 52 or 52 > 50
Order of Numbers

Ascending order: When the numbers are arranged from the smallest to the greatest,

it is called ascending order.
For example: 25, 36, 47, 68, 89, 90.

Descending order: When the numbers are arranged from the greatest to the
smallest, it is called descending order.

For example: 95, 76, 57, 38, 29, 12.
