Penjelasan dengan langkah-langkah:
[tex]1. \: \: \frac{4}{5} - \frac{4}{7} = \frac{28 - 20}{35} = \frac{8}{35} [/tex]
[tex]2. \: \: \frac{4}{10} - \frac{4}{16} = \frac{2}{5} - \frac{1}{4} = \frac{8 - 5}{20} = \frac{3}{20} \\ \\ yang \: \frac{4}{10} bisa \: disederhankan \: dulu \: dibagi \: 2 \\ \\ yang \: \frac{4}{16} juga \: bisa \: disederhanakan \: dibagi \: 4[/tex]
[tex]3. \: \: 15 \frac{2}{9} - 13 \frac{1}{8} = \frac{137}{9} - \frac{105}{8} = \frac{1.096 - 945}{72} = \frac{151}{72} = 2 \frac{7}{72} [/tex]
[tex]4. \: \: \frac{5}{6} - \frac{3}{10} - \frac{1}{4} = \frac{200 - 72 - 60}{240} = \frac{68}{240} = \frac{17}{60} [/tex]
[tex]5. \: \: \frac{14}{15} - \frac{8}{30} - \frac{1}{6} = \frac{28 - 8 - 5}{30} = \frac{15}{30} = \frac{1}{2} [/tex]
[tex]6. \: \: 8 \frac{11}{12} - 3 \frac{1}{4} - 2 \frac{2}{6} = \frac{107}{12} - \frac{13}{4} - \frac{14}{6} = \frac{107 - 39 - 28}{12} = \frac{40}{12} = \frac{10}{3} = 3 \frac{1}{3} [/tex]
SEMOGA MEMBANTU :D
