Like Decimal

Decimals having the same number of decimal places are called like decimals

Example:- (i) 3.1, 46.3, 1247.5, 437.0 are like decimals, each having 1 decimal places.

                 (ii) 2.68, 11.54, 0.79, 1.40 are like decimals, each having 2 decimal places.

Unlike Decimal

Some given decimals, all not having the same number of decimal places, are called unlike decimals.

Example:- (i) 4.38 and 43.8 are unlike decimals

                  (ii) 16.58m 9.637, 0.8 are unlike decimals

Conversion of Unlike Decimals to Like Decimals

Annexing zeroes to the extreme right of the decimal part of a decimal does not change its value.

e.g., 0.9 = 910 = 90100 = 0.90 and 0.90 = 90100 = 9001000 = 0.900

... 0.9 = 0.90 = 0.900, etc

mark me as brainliest.
