Fractions and Percentages play an important role to solve questions in Quantitative Aptitude. The meaning of fraction is to divide a whole thing into certain parts. There are some important and useful fractional values and their equivalent percentages are given.
$$\frac{1}{2}$$ = 50%
$$\frac{1}{3}$$ = 33.33%
$$\frac{1}{4}$$ = 25%
$$\frac{1}{5}$$ = 20%
$$\frac{1}{6}$$ = 16.67%
$$\frac{1}{7}$$ = 14.28%
$$\frac{1}{8}$$ = 12.5%
$$\frac{1}{9}$$ = 11.11%
$$\frac{1}{10}$$ = 10%
$$\frac{1}{11}$$ = 9.09%
$$\frac{1}{12}$$ = 8.33%
$$\frac{1}{13}$$ = 7.69%
$$\frac{1}{14}$$ = 7.14%
$$\frac{1}{15}$$ = 6.67%
$$\frac{1}{16}$$ = 6.25%
$$\frac{1}{17}$$ = 5.88%
$$\frac{1}{18}$$ = 5.56%
$$\frac{1}{19}$$ = 5.26%
$$\frac{1}{20}$$ = 5%
$$\frac{1}{21}$$ = 4.76%
$$\text{Percentage} = \frac{\text{Actual Value}}{\text{Total Value}}\times100$$
$$A\% \text{of} B = B\% \text{ of } A$$
If any two percentage namely P and Q are given then their successive percentage = $$P+Q+\frac{P \times Q}{100}$$
Q) Find out the value of 720 of 65%.
Sol. value of 720 of 65% = $$\frac{720}{100}\times65$$
= 468
Q) Find out the value of $$\frac{19}{16}$$ in the form of percentage.
Sol. value of $$\frac{19}{16}$$ = 118.75%
