[tex] \frac{4}{10} + 50\% = \frac{4}{10} + \frac{50}{100} = \frac{40}{100} + \frac{50}{100} = \frac{90}{100} = \frac{9}{10} \\ \frac{15}{20} + 12\% = \frac{15}{20} + \frac{12}{100} = \frac{75}{100} + \frac{12}{100} = \frac{87}{100} \\ \frac{16}{20} + 2\% = \frac{16}{20} + \frac{2}{100} = \frac{80}{100} + \frac{2}{100} = \frac{82}{100} = \frac{41}{50} \\ 40\% + \frac{4}{5} = \frac{40}{100} + \frac{4}{5} = \frac{40}{100} + \frac{80}{100} = \frac{120}{100} = \frac{6}{5} \\ 47\% + \frac{1}{10} = \frac{47}{100} + \frac{1}{10} = \frac{47}{100} + \frac{10}{100} = \frac{57}{100} \\ 55\% + \frac{1}{4} = \frac{55}{100} + \frac{25}{100} = \frac{80}{100} = \frac{4}{5} [/tex]
