Hasil dari 20persen + 0.45-1/2 adalah

20/100 + 45/100 - 1/2 = 20/100 + 45/100 - 50/100 = 15/100

Mathematics Is Love

[tex]20\% = \frac{20}{100} \\ 0.45 = \frac{45}{100} \\ \frac{1}{2} = \frac{50}{100} \\ jadi \: \frac{20}{100} + \frac{45}{100} - \frac{50}{100} = \frac{15}{100} \: atau \: \frac{3}{20} [/tex]
Semoga membantu
