In conversion of fraction to decimal fraction the rules are discussed here.
(i) If it is a proper fraction, write the numerator as a decimal.
(ii) If it is a mixed fraction, convert it to an improper fraction.
(iii) Divide as usual. Add as many zeroes after the decimal to the numerator as required, to complete the division.
Let us consider some of the examples:
(i) Convert ½ to decimal.
Solution:
1 ÷ 2
Therefore, ½ = 0.5
(ii) Convert 2/5 to decimal
Solution:
2 ÷ 5
Therefore, 2/5 = 0.4
(iii) Convert 7/8 to decimal
Solution:
7 ÷ 8
Therefore, 7/8 = 0.875
A whole number is a decimal with as many decimal places as required
For example:
4 = 4.0
= 4.00
= 4.000
= 4.0000
All the above are equal to whole number 4.
(iv) Convert 7 5/8 to decimal
Solution:
7 5/8
= (7 × 8 + 5)/8
= (56 + 5)/8
= 61/8
Therefore, 7 5/8 = 7.625
