Let’s learn how to compare bigger numbers.

Different number of digits Same number of digits
The number with more digits is always When the number of digits is same,

greater. start comparing the digits from the
leftmost digit.

Look at the given examples.

1. Compare 190 and 99. 2. Compare 89 and 101.

190 > 99 89 < 101

(3 digits) (2 digits) (2 digits) (3 digits)

3. Compare 125 and 200.

1 2 5 2 0 0

1 at the hundreds place 2 at the hundreds place

Since 2 > 1, 200 > 125.

4. Compare 198 and 189.

1 9 8 1 8 9

1 at the hundreds place 1 at the hundreds place

The digit at the hundreds place is same in both the numbers. Thus, compare
the digits at the tens place.

1 9 8 1 8 9

9 at the tens place 8 at the tens place

Since 9 > 8, 198 > 189.

5. Compare 125 and 127.

1 2 5 1 2 7

1 at the hundreds place 1 at the hundreds place

2 at the tens place 2 at the tens place

The digits at the hundreds and tens places are same in both the numbers.

Thus, compare the digits at the ones place.
Since 7 > 5, 125 < 127.
