Explain how comparing 645 and 738 different from comparing 645 and 649

For 645 and 738:

For these numbers we have that the difference between both is:

738 - 645 = 93

For 645 and 649:

For these numbers we have that the difference between both is:

649 - 645 = 4

Therefore, comparing the first two numbers of the second two numbers is different because the difference between the first two numbers is much larger.

Answer:

The difference between the first two numbers is much greater than the difference between the second two numbers.

Comparing 645 and 738 is different from comparing 645 from 649 in a few ways. So going in order of the three digits we can see that the 645 and 738 begin with different number, one has 6 one has a 7. In the second set, 645 and 649, of numbers both begin with a 6.

The second digits of the first number set also differ. One is a 3 the other contains a 4. In the second set of numbers the second digit is the same, both have a 4.

Lastly the third digit of the first set are also different, on being a 5 the other an 8. In the second set of numbers one of the third digit is a 5 the other is a 9.
