In 53.47, the decimal part is .47 and the digit in the tenths place is 4.

In 53.81, the decimal part is .81 and the digit in the tenths place is 8.

But 8 > 4

Therefore, 53.81 > 53.47

C. If the whole number part and the digit in the tenths place are the same, then compare the digit at
the hundredths place and so on.

3. Compare 81.39 and 81.37.

Solution:

In 81.39 and 81.37, the whole number part is the same, i.e., 81.

In 81.39 and 81.37, the decimal part in the tenths place is the same, i.e., 3

In 81.39, the decimal part is .39 and the digit in the hundredths place is 9.

In 81.37, the decimal part is .37 and the digit in the hundredths place is 7.

But 9 > 7

Therefore, 81.39 > 81.37

Ordering of Decimals:

In ordering decimals we will learn how to compare two or more decimals.

(i) Convert each of them as like decimals.

(ii) Compare these decimals just as we compare two whole numbers ignoring decimal point.

Example: Arrange in increasing order: 4.91, 13.01, 12.1, 18.123, 13.9, 4.53

Largest decimal places are in 18.123 that is 3

Therefore, convert each of the decimal number into like decimals with 3 decimal places.

4.91 = 4.910 ....... 2

13.01 = 13.010 ....... 4

12.1 = 12.100 ....... 3

18.123 = 18.123 ....... 6

13.9 = 13.900 ....... 5
