Here we discuss percentages only required for simplification problems, 

Percentages topic in detail will be discussed separately according to studyplan

Percentage Formula:

Example: what is 85 % of 680?

Trick 1 : Learning percentage to fraction conversion, helps you solve simplifications quickly

Some fractions are asked frequently, they are given below, learn them and remember them

½     = 50%
$\frac{1}{3} = 33\,\frac{1}{3}\%$	$\frac{2}{3} = 66\,\frac{2}{3}\%$
$\frac{1}{4} = 25\%$	$\frac{3}{4} = 75\%$
$\frac{1}{5} = 20\%$	$\frac{2}{5} = 40\%$	$\frac{3}{5} = 60\%$	$\frac{4}{5} = 80\%$
$\frac{1}{6} = 16\,\frac{2}{3}\%$	$\frac{5}{6} = 83\,\frac{1}{3}\%$
$\frac{1}{7} = 14\,\frac{2}{7}\%$	$\frac{2}{7} = 28\,\frac{4}{7}\%$	$\frac{3}{7} = 42\,\frac{6}{7}\%$	$\frac{4}{7} = 57\,\frac{1}{7}\%$
		$\frac{5}{7} = 71\,\frac{3}{7}\%$	$\frac{6}{7} = 85\,\frac{5}{7}\%$
$\frac{1}{8} = 12\,\frac{1}{2}\%$	$\frac{3}{8} = 37\,\frac{1}{2}\%$	$\frac{5}{8} = 62\,\frac{1}{2}\%$	$\frac{7}{8} = 87\,\frac{1}{2}\%$
$\frac{1}{9} = 11\,\frac{1}{9}\%$	$\frac{2}{9} = 22\,\frac{2}{9}\%$	$\frac{4}{9} = 44\,\frac{4}{9}\%$	$\frac{5}{9} = 55\,\frac{5}{9}\%$
		$\frac{7}{9} = 77\,\frac{7}{9}\%$	$\frac{8}{9} = 88\,\frac{8}{9}\%$
$\frac{1}{10} = 10\%$	$\frac{3}{10} = 30\%$	$\frac{7}{10} = 70\%$	$\frac{9}{10} = 90\%$
$\frac{1}{11} = 9\,\frac{1}{11}\%$	$\frac{2}{11} = 18\,\frac{2}{11}\%$	$\frac{3}{11} = 27\,\frac{3}{11}\%$	$\frac{4}{11} = 36\,\frac{4}{11}\%$
$\frac{1}{12} = 8\,\frac{1}{3}\%$
