Equivalent decimal fractions are unlike fractions which are equal in value.
Let us consider the following examples:
(i) 0.4, 0.40, 0.400, 0.4000
Each of the above is equal to 0.4 or 4/10.
(ii) 1.9, 1.90, 1.900, 1.9000
Each of the above is equal to 1.9 or 19/10.
(iii) 10.14, 10.140, 10.1400, 10.14000
Each of the above is equal to 10.14 or 1014/100.
(iv) 0.94, 0.940, 0.9400, 0.94000
Each of the above is equal to 0.94 or 94/100.
(v) 9.1, 9.10, 9.100, 9.1000
Each of the above is equal to 9.1 or 91/10.
(vi) 60.49, 60.4900, 60.490
Each of the above is equal to 60.49 or 6049/100.
Similarly, we have
0.300 = 0.30 = 0.3
0.700 = 0.70 = 0.7
0.200 = 0.20 = 0.2
Thus,
by adding any number of zeros after the extreme right digit in the
decimal part of a decimal number does not change the value of the
number.
Numbers obtained by inserting zeros after the extreme
right digit in the decimal part of a decimal number are known as
equivalent decimals.
Hence, 0.75, 0.750, 0.7500 etc are equivalent decimals.
