hasil dari tiga per lima dikurangi dua puluh persen ditambah nol koma delapan puluh lima

3/5 - 20 % + 0,85

[tex] = ( \frac{3 \times 20}{5 \times 20} ) - 20\% + 85\% \\ \\ = 60\% - 20\% + 85\% \\ \\ = 40\% + 85\% \\ \\ = 125\%[/tex]

[tex] \frac{3}{4} - \frac{20}{100} + \frac{85}{100} = \frac{60}{100} - \frac{20}{100} + \frac{85}{100} = \frac{125}{100} = 1 \frac{25}{100} = 1 \frac{1}{4} [/tex]
