Hasil dari 5 1/6 - 2 1/4 + 2/3 - 11/12adalah.....
[tex]5 \frac{1}{6} - 2 \frac{1}{4} + \frac{2}{3} - \frac{11}{12} [/tex]
- [tex]= \frac{5 \times 6 + 1}{6} - \frac{2 \times 4 + 1}{4} + \frac{2}{3} - \frac{11}{12} [/tex]
- [tex]= \frac{30 + 1}{6} - \frac{8 + 1}{4} + \frac{2}{3} - \frac{11}{12} [/tex]
- [tex]= \frac{31}{6} - \frac{9}{4} + \frac{2}{3} - \frac{11}{12} [/tex]
- [tex]= \frac{31 \times 2 - 9 \times 3 + 2 \times 4 - 11 \times 1}{12} [/tex]
- [tex]= \frac{62 - 27 + 8 - 11}{12} = \frac{32}{12} = \frac{8}{3} = 2 \frac{2}{3} [/tex]
