Conversion of Unlike Decimal Numbers into Like Decimal Numbers

Mathematics Class IV Decimals 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.

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 $= 3 - 1 = 2$
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.
