pengurangan tiga pecahan berturut-turut dari soal 35 5 per 7 dikurang 12 satu per 2 dikurang 8 1 per 4

[tex]35 \frac{5}{7} = \frac{250}{7} \\ 12 \frac{1}{2} = \frac{25}{2} \\ 8 \frac{1}{4} = \frac{32}{4 } \\ \\ \frac{250}{7} - \frac{25}{2} - \frac{32}{4} \\ \\ = \frac{250 \times 2}{7 \times 2} - \frac{25 \times 7}{2 \times 7} - 8 \\ = \frac{500}{14} - \frac{175}{14} - \frac{8 \times 14}{1 \times 14} \\ = \frac{500}{14} - \frac{175}{14} - \frac{112}{14} \\ = \frac{500 - 175 - 112}{14} \\ = \frac{213}{14} \\ = 15 \frac{3}{14} [/tex]
