greatest aND smallest Numbers
Let us find the greatest number among 7,839; 999 and 5,326. th H t O
Step 1: Arrange the numbers in the place value chart. 7 8 3 9
Step 2: Cross the smallest number (999) from the group. 9 9 9
5 3 2 6
7,839 999 5,326
Step 3: Out of the remaining two numbers, compare which is the greater number. In this
case, 7,839 is greater than 5,326.
Step 4: Thus, 7839 is the greatest number among 7,839; 999 and 5,326.
example 1: Find the greatest number among 4,562; 1,234 and 2,076.
Solution: Step 1: Arrange the numbers in the place value chart. th H t O
Step 2: Cross the smallest number (1,234) from the group.
4 5 6 2
4,562 1,234 2,076 1 2 3 4
Step 3: Out of the remaining two numbers, compare which 2 0 7 6
is the greater number. In this case, 4,562 is greater than 2,076.
Step 4: Thus, 4,562 is the greatest number among 4,562; 1,234 and 2,076.
example 2: Find the smallest number among 4,215; 6,738 and 9,831.
Solution: Step 1: Arrange the numbers in the place value chart.
Step 2: Cross the greatest number (9831) from the group. th H t O
4 2 1 5
4,215 6,738 9,831 6 7 3 8
Step 3: Out of the remaining two numbers, compare which 9 8 3 1
is the greater number. In this case, 6,738 is greater
than 4,215 or you may say 4,215 is smaller than 6,738.
Step 4: Thus, 4,215 is the smallest number among 4,215; 6,738 and 9,831.
orDeriNg oF Numbers
We arrange the numbers in increasing order, that is, from the smallest to the greatest; it is
called ascending order. Ritvik noted down the numbers from the number plates of four cars.
The numbers are 2,937, 6,543, 1,359 and 5,023. th H t O
He wants to arrange the numbers in a particular order. 2 9 3 7
First, he writes the given numbers in the place value chart and 6 5 4 3 Greatest
1 3 5 9
Smallest
then starts comparing. 5 0 2 3
Looking at the thousands place digits, 2, 6, 1 and 5; he finds that 1 < 2 < 5 < 6.
Thus, the four numbers in ascending order will be arranged as:
1,359 < 2,937 < 5,023 < 6,543
