hasil dari a. 4%+0.5+2/3, b2/5+5%+2.5 , c. 80%-0.5-2/10

[tex]a. \: 4\% + 0.5 + \frac{2}{3} = \frac{4}{100} + \frac{5}{10} + \frac{2}{3} = \frac{12 + 120 + 200}{300} = \frac{362}{300} = 3 \frac{31}{150} \\ b. \: \frac{2}{5 } + 5\% + 2.5 = \frac{2}{5} + \frac{5}{100} + \frac{25}{10} = \frac{40 + 5 + 250}{100} = \frac{295}{100} = 2 \frac{19}{20} \\ c. \: 80\% - 0.5 - \frac{2}{10} = \frac{80}{100} - \frac{5}{10} - \frac{2}{10} = \frac{80 - 50 - 20}{100} = \frac{10}{100} = \frac{1}{10} [/tex]
