Conversion of Unlike Decimal Numbers into Like Decimal Numbers

\bullet Like and unlike decimal numbers are similar to Like and unlike fractions. Let’s have a look at some examples.

\dfrac{5}{10},\ \dfrac{7}{10},\ \dfrac{8}{10},\ \dfrac{9}{10},\ \dfrac{15}{10} are like fractions.

If we convert these like fractions to decimals, then they will be known as like decimal numbers.

0.5,\ 0.7,\ 0.8,\ 0.9,\ 1.5 are like decimal numbers.

\dfrac{5}{10},\ \dfrac{7}{100},\ \dfrac{125}{1000} are unlike fractions.

If we convert these unlike fractions into decimal format, then they will become unlike decimals.
0.5,\ 0.07,\ 0.125 are unlike decimal numbers.

\bullet While converting unlike decimals into like decimals we must do the following things. Let us consider unlike decimal 0.8 and 0.315 for conversion.

  1. count the digits present after the decimal point for both the numbers and find out the difference.
       Number of decimal digits present in 0.8 = 1
       Number of decimal digits present in 0.315 = 3
       Difference in decimal digits between two decimal numbers = 3 - 1 = 2
  2. Here 0.8 is having less decimal digits.
    Add two zeros to the extreme right of 0.8 = 0.800
    Now, 0.800 and  0.315 became like decimal numbers.
