bantu jawabannya ya besok mau dikumpulin pakai cara ya sekian terima kasih ​

[tex]6. \: \: (2 \frac{1}{2} \div 1 \frac{1}{4} )- 2 \frac{1}{8 } \\ \\ = ( \frac{5}{2} \div \frac{5}{4} ) - \frac{17}{8} \\ \\ = ( \frac{5}{2} \times \frac{4}{5} ) - \frac{17}{8} \\ \\ = 2 - \frac{17}{8} \\ \\ = \frac{16 - 17}{8} = - \frac{1}{8} [/tex]

[tex]7. \: \: \frac{6}{8} \times \frac{2}{3} + ( \frac{3}{2} - \frac{1}{4} ) \div \frac{1}{2} \\ \\ = \frac{3}{4} \times \frac{2}{3} + ( \frac{6 - 1}{4} ) \div \frac{1}{2} \\ \\ = (\frac{3}{4} \times \frac{2}{3} )+ \frac{5}{4} \div \frac{1}{2} \\ \\ = \frac{1}{2} + ( \frac{5}{4} \times \frac{2}{1} ) \\ \\ = \frac{1}{2} + \frac{5}{2} = \frac{6}{2} = 3[/tex]

[tex]8. \: \: 25\% \times \frac{5}{6} + 0.20 \\ \\ = \frac{25}{100} \times \frac{5}{6} + \frac{20}{100} \\ \\ = (\frac{1}{4} \times \frac{5}{6} ) + \frac{1}{5} \\ \\ = \frac{5}{24} + \frac{1}{5} = \frac{25 +24 }{120} \\ \\ = \frac{49}{120} [/tex]
