Like Decimal Fractions

Like Decimal Fractions are discussed here.

Two or more decimal fractions are called like decimals if they have equal number of decimal places. However the number of digits in the integral part does not matter.

0.43, 10.41, 183.42, 1.81, 0.31 are all like fractions because they all have 2 decimal places. But 74.18 and 74.193are not like decimals as 74.18 has two decimal places and 74.193 have three places of decimal.

(i) 1.12, 0.45, 15.65 and 110.01 are all like decimal fractions because they all have 2 decimal places.

(ii) 21.1, 710.2, 1.6 and 100.1 are all like decimal fractions because they all have 1 decimal place.

(iii) 1.117, 61.009, 477.015 and 1201.001 are all like decimal fractions because they all have 3 decimal places.

(iv) 33.333, 34.001, 89.435 and 41.009 are all like fractions because they all have 3 decimal places.
