Question

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

Answer 1

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.

Answer 2

Answer: Comparing both the pairs of number is different as difference in first pair is greater than difference in the second pair.

Step-by-step explanation:

At first pair we can see that the 645 and 738 begin with different numbers, one has 6 and other has  7.  In middle, one has 4 and the other has 3.  At last, one has 5 and the other has 8.  

So to find difference we need to subtract by taking carry, we get

738-645=93

In the second pair,645 and 649, begin with same number 6. In middle, Both have 4. At last, one has 5 and other has 9.  

To find difference we need to just find the difference between the third digit as other are same.

Therefore 649-645=4

So comparing both the pairs of number is different as difference in first pair is greater than difference in the second pair.
