ARRANGE DECIMAL NUMBER IN ASCENDING ORDER

ARRANGE DECIMAL NUMBER IN ASCENDING ORDER -

Earlier we have learn, how to arrange digit or numbers in small to big (Ascending) orders. Now we will learn how to arrange decimal numbers in ascending order.

Rules or steps for finding decimal number in ascending order

Step.1) Write the decimal fractions one below the other column wise.

Step.2) Convert all decimal numbers into highest decimal places.

Step.3) Compare each place value and then arrange from small to big.

Step.4) Write the answers using the greater than ( > ) or less than ( < ) sign.


Example.1) Arrange the numbers 0.7, 0.962, 1.05, 0.89, 2.354, 1.09, 42.1, 0.98, 5.238, 6.32 in ascending order. Also find smallest and biggest number.

decimal

As you can see from the above table, we have converted all the given decimal number into highest decimal places.

Step.1) Write the given decimal fractions one below the other as shown above, column wise.

Step.2) The highest decimal place is 3, so convert the rest decimals to 3 decimal places.

Step.3) Compare each place value and then arrange from small to big.

So, the given numbers in ascending orders are - 0.7, 0.89, 0.962, 0.98, 1.05, 1.09, 2.354, 5.238, 6.32, 42.1  

Step.4) Write the answers using the greater than ( > ) or less than ( < ) sign.

        So, as per ascending (small to big) order we have - 

0.7 < 0.89 < 0.962 < 0.98 < 1.05 < 1.09 < 2.354 < 5.238 < 6.32 < 42.1       

So, the smallest number is 0.7 and the biggest number is 42.1 (Ans.)



Example.2) Arrange the numbers 123.86, 25.9, 11.05, 9.898, 29.35, 1.093, 42.457, 78.98, 54.287, 69.32 in ascending order. Also find smallest and biggest number.

Step.4) Write the answers using the greater than ( > ) or less than ( < ) sign.

        So, as per ascending (small to big) order we have - 

1.093 < 9.898 < 11.05 < 25.9 < 29.35 < 42.457 < 54.287 < 69.32 < 78.98 < 123.86

So, the smallest number is 1.093 and the biggest number is 123.86 (Ans.)
