## Two-Digit Numbers – Definition

Two-digit numbers have two digits. The last digit from the right-hand side represents one’s place and the other digit represents tens place. Two-digit numbers start from 10 and end with 99. Example of two-digit numbers are 10,14, 17, 19, 25, 50, 100 etc.

### How do you Compare Two-Digit Numbers?

When comparing two-digit numbers we use greater than symbol(>) for greater values and less than a symbol for lesser values. When both the numbers are equal then we use equal to (=). The two other symbols used for comparison are â‰¥ (greater than or equal to) and â‰¤ (less than or equal to).

- The number which has greater valued digit at tenâ€™s place is greater as compared to other:85 > 24, 98 > 53 , 65 > 29 ,72>33,49>14 etc.
- Â If the digits at tenâ€™s place of both the numbers are equal, then the digits at oneâ€™s place of both the numbers are compared. The number which has the greater digit at oneâ€™s place is greater than the other.43>42, 65>61, 15>11,29>25,38>36 etc.consider other examples on comparison of two-digit numbers.

### Comparing 2 Digit Numbers Examples

**Example 1.**

Compare Two-digit numbers 72, 47.

**Solution:**

In 72 7 is in the tens place and 2 is in one’s place.

In 47 4 is in the tens place and 7 is in one’s place.

When we compare tens place of both the numbers 7>4.So 72>47.

**Example 2.**

Compare two digit numbers 95, 68.

**Solution:**

In 95 9 is in the tens place and 5 is in one’s place.

In 68 6 is in the tens place and 8 is in one’s place.

when we compare tens place of both the numbers 9>6.So 95>68.

**Example 3.**

Compare two digits 65, 84.

**Solution:**

In 65 6 is in the tens place and 5 is in one’s place.

In 84 8 is in the tens place and 4 is in one’s place.

when we compare tens place of both the numbers 8>6.So 84>65

**Example 4.**

Compare two digits 69, 63.

**Solution:**

In 69 6 is in the tens place and 9 is in one’s place.

In 63 6 is in the tens place and 3 is in one’s place.

When we compare, tens place of both the numbers are same i.e.Â 6. so compare one’s digit of both the numbers. one’s digit of 69 is 9 and one’s digit of 63 is 3.

9>3.

So 69 is greater than 63.

**Example 5.**

Compare two digit numbers 81, 85.

**Solution:**

In 81 8 is in the tens place and 1 is in one’s place.

In 85 8 is in the tens place and 5 is in one’s place.

when we compare, the tens place of both the numbers is the same. Compare one’s place of both the numbers5>1. So 85 is greater than 81.

**Example 6.**

Compare two digit numbers 71, 78?

**Solution:**

In 71 7 is in the tens place and 1 is in one’s place.

In 78 7 is in the tens place and 8 is in one’s place.

when we compare, the tens place of both the numbers is the same. compare one’s place of both the numbers8>1. So 78 is greater than 71.

Two-Digit numbers are always greater than the one-digit number. Consider the following examples

15>9, 25>5, 33>6, 68>8, 18>9, 12>4 etc.

Numbers can be arranged in two ways. One is in Ascending Order and the other one is Descending Order.

### Arranging 2 Digit Numbers in Ascending Order

Ascending order means to arrange numbers from smallest to largest. i.e. smaller digit numbers come first and then larger numbers.

For example Arrange the numbers 15,92,27,87,62,23,48,63,76 in ascending order.

Ascending order are 15, 23,27, 48,62, 63, 76,

Arrange the numbers 12,22,66,43,56,85,14,10,38 in ascending order.

Ascending order are 10, 12, 14, 22, 38, 43, 56, 66, 85.

Arrange the numbers 52,22,66,14,56,85,64,70,38 in ascending order.

Ascending order are 14, 22, 38, 52, 56, 64, 66, 70, 85.

Arrange the numbers 85,12,76,41,96,58,44,20,68 in ascending order.

Ascending order are 12, 20, 41, 44, 58, 68, 76, 85, 96.

### Arranging 2 Digits Numbers in Descending Order

Descending order means arranging numbers from largest to smallest. i.e. larger digit numbers come first and then smaller numbers.

Consider the following examples

Arrange the numbers 75,32,66,11,96,58,34,20,48 in Descending order.

Descending order are 96, 75, 66, 58, 48, 34, 32, 20, 11.

Arrange the numbers 15,72,66,11,69,28,54,20,98 in Descending order.

Descending order are 98, 72, 69, 66, 54, 28, 20, 15, 11.

Arrange the numbers 13,32,46,10,29,78,42,60,88 in Descending order.

Descending order are 88, 78, 60, 46, 42, 32, 29, 13, 10.

Arrange the numbers 18,62,36,48,29,78,42,20,80in Descending order.

Descending order are 80, 78, 62, 48, 42, 36, 29, 20, 18.
