If other decimals are also changed into equivalent decimals with 3 decimal places, all of them will
become like decimals with 3 decimal places.

Therefore, 14.300, 8.140 and 7.195 are like decimals.

Hence we conclude that,

(i) to find the number of decimal places in the decimal with the largest number of decimal places.

(ii) change the other decimals into their equivalent decimals which have the same number of decimal
places as the decimal with the largest number of decimal places.

Two or more decimal fractions are called unlike decimals if they have unequal numbers of decimal
places.

Let us consider some of the unlike decimals;

(i) 8.4, 8.41, 8.412

In 8.4, 8.41, 8.412 the number of decimal places are 1, 2 and 3.

(ii) 80.41, 182.415

In 80.41, 182.415 the number of decimal places are 2 and 3.

(iii) 0.129, 0.12, 0.1

In 0.129, 0.12, 0.1 the number of decimal places are 3, 2 and 1.

0.1, 0.10, 0.100 are equivalent but unlike decimals, therefore unlike decimals may or may not be
equivalent decimals.
