(Percentage fraction conversion table)

Remember: 

1/7 = 14.28%  and  1/14 = 7.14%

1/6 = 16.66% and  1/15 = 6.66%

1/9 = 11.11% and  1/11 = 9.09%

1/15 = 6.66% and 1/16 = 6.25%

1/3 = 33.33% and 3/10 = 30%

99.99% is equivalent to 100% ( in calculation)

Some  other typical values

1/13 = 7.69% = 7.7%,     1/17 = 5.88%,  1/19 = 5.26%,

1/21 = 4.76%,   1/23 = 4.35%,  1/24 = 41.66%

Learning from the table :

i) This table is a first hand support as a percentage values of some frequently used fractions.

ii) All the percentage values whose decimal part in 0.33, 0.66, 0.00 contain the denominator 3 in the fraction.

iii) Similarly if there is 0.16, 0.33, 0.50, 0.66, 0.83, 0.00 it means there is a 6 in the denominator of the fraction.

iv) Similarly if there is 0.28, 0.56, 0.85, 0.13, 0.42, 0.71 it means there is a 7 as denominator.

v) If there is 0.11, 0.22, 0.33, 0.44.....0.99 etc. It means there is 9 as the denominator of the fraction.

vi) If there is 0.09, 0.18, 0.27... it means there is 11 as the denominator of the fraction.

vii) If two percentage values have different decimal values ( there must be different denominators) then their addition or subtraction results always in decimal i.e., never as an integer.
