Concept of like and unlike decimals:
Decimals having the same number of decimal places
are called like decimals i.e. decimals having the same number of digits on the
right of the decimal point are known as like decimals. Otherwise, decimals not
having the same number of digits on the right of the decimal point are unlike
decimals.
Examples on like and unlike decimals:
5.45, 17.04, 272.89, etc. are like decimals as all these decimal numbers are written up to 2 places of decimal.
7.5, 23.16, 31.054, etc. are unlike decimals. As in 7.5 has
one decimal place. 23.16 has two
decimal places. 31.054 has three decimal places
Note:
If we put any number of annexing zeroes on the right side of the
extreme right digit of the decimal part of a number does not alter the value of
the number. So, unlike decimals can always be converted into like decimals by
annexing required number of zeros on the right side of the extreme right digit
in the decimal part.
For example;
9.3, 17.45, 38.105 are unlike decimals. These decimals can be rewritten as
9.300, 17.450, 38.105 so now, these are like decimals.
Suppose 0. 1 = 0. 10 = 0. 100 etc, 0.5 = 0.50 = 0.500 etc, and so on. That is
by annexing zeros on the right side of the extreme right digit of the decimal
part of a number does not alter the value of the number.
Unlike decimals may be converted into like decimals by annexing the requisite
number of zeros on the right side of the extreme right digit in the decimal
part.
