26. B) 225.000-15%=191. 250

[tex]26. \: \: 15\% = \frac{15}{100} \\ \frac{15}{100} \times 225.000. = 33.750 \\ 225.000 - 33.750 = 191.250 \\ jadi \: jawabannya \: b.191.250 \\ \\ 27.\: \: \: 0.8 = \frac{8}{10} \\ \: \: \: \: \: \: \: \: \: 60\% = \frac{60}{100} \\ \frac{8}{10} \div \frac{3}{4} \div \frac{60}{100} = \frac{16}{9} \\ kalo \: diperkecil \: jadi \: 1 \frac{7}{9} \\ jawabannya \: c \\ \\ \\ 28. \: 3 \times \frac{3}{9} \times \frac{4}{7} \\ = 3 \times \frac{ 4}{21} \\ = \frac{4}{7} \\ jawabannya \: b \\ \\ 29 \: \: 5 \frac{3}{4} = \frac{15}{4} \\ = \frac{15}{4} - (2.5 + 25\%) \\ = \frac{15}{4} - \frac{11}{4 } \\ = 1 \: jawabannya \: a[/tex]
