example 4: Which is greater: 372.437 or 372.438.
H t O • t h th
Solution: 372.437 and 372.438 are like decimals. 3 7 2 • 4 3 7
Whole number parts of both decimals are
same. Tenths and hundredths digits of 3 7 2 • 4 3 8
decimal parts are also same. On comparing Same 8 > 7
thousandths place digits, we get

7 thousandths < 8 thousandths.
So, 372.437 < 372.438

Thus, 372.438 > 372.437.
example 5: Arrange the following decimals in ascending order: 0.6, 0.73, 0.008, 0.062.

Solution: Converting unlike decimals into like decimals, we have O • t h th

0.600, 0.730, 0.008, 0.062 0 • 6 0 0

The ascending order of the decimals is 0 • 7 3 0

0.008 < 0.062 < 0.600 < 0.730 0 • 0 0 8
or 0.008 < 0.062 < 0.6 < 0.73. 0 • 0 6 2
