Hej!
[tex]5\% = \frac{5}{100} = \frac{5 \div 5}{100 \div 5} = \frac{1}{20} \\ \\ 30\% = \frac{30}{100} = \frac{30 \div 10}{100 \div 10} = \frac{3}{10} \\ \\ 45\% = \frac{45}{100} = \frac{45 \div 5}{100 \div 5} = \frac{9}{20} \\ \\ 85\% = \frac{85}{100} = \frac{85 \div 5}{100 \div 5} = \frac{17}{20} [/tex]
