##### General Method of Converting a Common Fraction into a Decimal Fraction

To convert a common fraction into a decimal fraction, we adopt the division method. In this method, we use the following steps:

Step-1: Divide the numerator by the denominator till a non-zero remainder is obtained.

Step-2: Put a decimal point in the dividend as well as in the quotient.

Step-3: Put a zero on the right of the decimal point in the dividend as well as on the right of the remainder.

Step-4: Divide again just as we do in whole numbers.

Step-5: Repeat step 4 till the remainder is zero.

Example:

Convert 3/4 into decimals.

Divide the numerator 3 by the denominator 4.

¾ = 3.00/4 = 0.75

##### Convert 9(8/25) into decimal fractions.

9(8/25) can be written as (9 x 25 + 8)/25 = 233/25 = (233 x 4)/ (25 x 4) = 932/100 = 9.32

##### Some Uses of Decimal Notation

Example:

Express in kilometres, using decimals:

(i) 8 km 56 m (ii) 853 m

(i)8 km 56 m = 8 km + 56 m

8 km + 56/1000 km (Because 1meter = 1/1000 km)

= 8 km + 0.056 km = 8.056 km

(ii) 853 m = 853/1000 = 0.853 km

##### Express in kilograms, using decimals: (i) 3 kg 222 g (ii) 8 g

(i) 3 kg 222 g = 3 kg + 222 g

= 3 kg + 222/1000 (because 1 g = 1/1000 kg)

= 3.222 kg

(ii) 8 g = 8/1000 = 0.008 kg

##### How do I convert a fraction to a decimal?

(i) In fractions, the numerator is the number above the line and the denominator is the number below.

(ii) The line in a fraction that separates the numerator and the denominator represents division.

(iii) To convert a fraction to a decimal, divide the numerator by the denominator.

##### What is decimal value of 1/3?

To convert 1/3 to a Decimal

1.0000 = 0.333 (accurate to only 3 decimal places)

##### What is called decimal fraction?

A fraction where the denominator (the bottom number) is a power of ten (such as 10, 100, 1000, etc). You can write decimal fractions with a decimal point (and no denominator), which make it easier to do calculations like addition and multiplication on fractions.
