 9000 \(+\) 100 \(+\) 130
Solution:
9000 \(+\) 100 \(+\) 13 \(=\) 9113
Answer:
(2) 9000 \(+\) 100 \(+\) 13
2. Comparing And Ordering Numbers
When we compare numbers, we will compare the digits from the left to the right.
The greater the digit on the “left”, the greater the number.
Question 1:
Let’s take a look at the following numbers:
Which number is greater?
Solution:
The digit in the thousands place of both numbers is 2.
Since they are the same, we look at the digit in the hundreds place.
The digit in the hundreds place of both numbers is different. We compare them.
Since 9 is greater than 5, 2950 is greater than 2590.
Answer:
2950
Question 2:
Which of the following is the greatest?
 6710
 2375
 4097
 1684
Solution:
By comparing the digits in the thousands place for all the numbers, 6 is the greatest.
Hence, 6710 is the greatest number.
Answer:
(1) 6710
Question 3:
Which of the following is the smallest?
 7835
 1089
 2550
 4872
Solution:
By comparing the digits in the thousands place for all the numbers, 1 is the smallest.
Hence, 1089 is the smallest number.
Answer:
(2) 1089
Question 4:
Which of the following is the greatest?
 5760
 5670
 6750
 6570
Solution:
By comparing the digits in the thousands place for all the numbers, 6 is greater than 5.
Hence, we compare 6750 and 6570.
By comparing the digits in the hundreds place for 6750 and 6570, 7 is greater than 5.
Hence, 6750 is the greatest number.
Answer:
(3) 6750
Question 5:
Which of the following is the smallest?
 2323
 2332
 3232
 3223
Solution:
By comparing the digits in the thousands place for all the numbers, 2 is smaller than 3.
Hence, we compare 2323 and 2332.
The digit in the hundreds place for 2323 and 2332 is the same. By comparing the digits in the tens place for 2323 and 2332, 2 is smaller than 3.
Hence, 2323 is the smallest number.
Answer:
(1) 2323
