Decimals least to Greatest


We have learnt the fractions in the lower class mathematics. Now we shall study about special fractions whose denominators are 10, 100, 1000 etc. These fractions are called decimal fractions. Decimals least to greatest is also called as decimals in ascending order (Lower value to higher value)

Let us these fractions in a new way. That is

1/10 is understand writing one-tenth and is correspond to in decimal fraction as 0.1

1/100 is understand writing as one-hundredth and is correspond to in decimal fraction as 0.01

1/1000 is understand writing as one-thousandth and is correspond to in decimal fraction as 0.001

Steps for Calculating Decimals least to Greatest:

Step 1: Look the whole number first, and then look at the tenth, then the hundredth place and so on.

Step 2: Find out which number is smallest

Step 3: Arrange the decimals from least to greatest

For example, arrange the following numbers from least to greatest

0.56, 0.102, 0. 272, 0.5

Ans:  0.102, 0.272, 0.5, 0.56

Examples on Decimals least to Greastest:

Let us see some examples of decimal least to greatest:

Ex 1:  Find order of the decimals from least to greatest

5.6, 2.5, 1.2, 6.5, 0.6 and 0.2

Sol :   Step 1: First look at the tenth, and then the hundredth place so on. Next find the compare the two decimal numbers.

6.5 > 5.6

5.6 > 2.5

2.5 > 1.2

1.2 > 0.6

0.6 > 0.2

Step 2:  Arrange the decimals from least to greatest.

0.2, 0.6, 1.2, 2.5, 5.6 and 6.5

The above values are the arranged values from least to greatest.

Ex  2:   Find order of the decimals from least to greatest

5.7, 57, 0.71, 0.26

Sol :  Step 1: First look at the tenth, and then the hundredth place so on. Next find the compare the two decimal numbers.

56 > 5.7

5.7 > 0.71

0.71 > 0.26

Step 2:  Arrange the decimals from least to greatest.

0.26, 0.71, 5.7, 57

The above values are the arranged values from least to greatest.
