Jawaban:

$7. : (7 frac{1}{4} + 2 frac{1}{2} - 1 frac{1}{4} ) div 4 \ = (frac{29}{4} + frac{5}{2} - frac{5}{4} ) div frac{4}{1} \ = (frac{29 + 10 - 5}{4} ) div frac{4}{1} \ = frac{34}{4} times frac{1}{4} = frac{34}{16} = 2 frac{2}{16} = 2 frac{1}{8} \ \ 8. : 1 frac{1}{5} div frac{1}{5} = frac{6}{5} times frac{5}{1} = frac{30}{5} = 6 : gelas \ \ 9. : 4 frac{1}{2} div 4 = frac{9}{2} div frac{4}{1} = frac{9}{2} times frac{1}{4} = frac{9}{8} = 1 frac{1}{8} \ \ 10. : 30 times frac{2}{4} = frac{60}{4} = 15 : kg \ 15 div 5 = 3 : kg$
