Verified answer

[tex] \frac{28}{35} \times 100\% = \frac{4}{5} \times 100\% = 80\%[/tex]

[tex] \frac{75}{33} \times 100\% = \frac{25}{11} \times 100\% = 227.(27)\%[/tex]

[tex] \frac{12.5}{8.75} \times 100\% = \frac{1250}{875} \times 100\% = \\ \frac{10}{7} \times 100\% = 142.857...\%[/tex]

[tex] \frac{50}{62.5} \times 100\% = \frac{500}{625} \times 100\% = \frac{4}{5} \times 100\% = 80\%[/tex]
