Comparison of 2-digit Numbers

We compare numbers by comparing their tens and ones digits.

To compare 2-digit numbers (10 to 50), we follow these steps.

Step 1. Compare the digits at tens place. The number with

greater tens digit is larger.

Step 2. If tens digits are equal, compare the digits at ones

place. The number with greater ones digit is larger.

Let us compare 34 and 28.

34 3 tens 4 ones 2 tens 8 ones 28

3 tens > 2 tens

So, 34 > 28

Let us compare 23 and 25.

23 25
2 tens 3 ones 2 tens 5 ones

2 tens = 2 tens

3 ones < 5 ones

So, 23 < 25
