MARK MY ANSWER AS BRAINLIEST PLEASE

Step-by-step explanation:

$(i) \: 20\% = \frac{20}{100} = \frac{1}{5} \\ \: (ii)80\% = \frac{80}{100} = \frac{4}{5} \\ (iii)\: 42\% = \frac{42}{100} = \frac{21}{50}$

$(iv)63\% = \frac{63}{100} = \frac{63}{100} \\ (v) 12.5\% = \frac{12.5}{100} = \frac{25}{2} \\( vi)95\% = \frac{95}{100} = \frac{19}{20}$

$(vii) 0.05\% = \frac{0.05}{100} = \frac{1}{20} \\( viii)135\% = \frac{135}{100} = \frac{27}{20}$
