4/10 + 50% 15/20 + 12% 16/20 + 2% Tolong pakai cara perpecahan biasa dengan persen

[tex] \frac{4}{10} + \frac{50}{100} = \frac{40}{100} + \frac{50}{100} \\ = \frac{90}{100} = 90\% = \frac{9}{10} \\ \frac{15}{20} + \frac{12}{100} = \frac{75}{100} + \frac{12}{100} \\ \frac{87}{100} = 87\% \\ \frac{16}{20} + \frac{2}{100} = \frac{80}{100} + \frac{2}{100} \\ \frac{82}{100} = 82\%[/tex]
maaf kalau salah
