Penjelasan dengan langkah-langkah:

$1. : : 1 frac{1}{3} times frac{1}{7} \ = frac{4}{3} times frac{1}{7} \ frac{4 times 1}{3 times 7} \ = frac{4}{21} \ \ 2. : : 1 frac{1}{4} times frac{2}{3} \ = frac{5}{4} times frac{2}{3} \ = frac{5 times 2}{4 times 3} \ = frac{10 }{12} \ = frac{5}{6} \ \ 3. : : 1 frac{2}{4} times frac{2}{8} \ = frac{6}{4} times frac{2}{8} \ = frac{6 times 2}{4 times 8} \ = frac{12}{32} \ = frac{6}{16} \ = frac{3}{8} \ \ 4. : : 2 frac{1}{3} times frac{3}{4} \ = frac{7}{3} times frac{3}{4} \ = frac{7 times 3}{3 times 4} \ = frac{21}{12} \ \ 5. : : 3frac{1}{4} times frac{7}{8} \ = frac{13}{4} times frac{7}{8} \ = frac{13 times 7}{4 times 8} \ = frac{91}{32} \ \ 6. : 1 frac{1}{4} times 1 frac{1}{2} \ = frac{5}{4} times frac{3}{2} \ = frac{5 times 3}{4 times 2} \ = frac{15}{8} \ \ 7. : : 2 frac{1}{3} times 2 frac{1}{7} \ = frac{7}{3} times frac{15}{7} \ = frac{7 times 15}{3 times 7} \ = frac{105}{21} \ = frac{35}{7} \ = frac{5}{1} \ \ 8. : : 2 frac{1}{5} times 2 frac{2}{6} \ = frac{11}{5} times frac{14}{6} \ = frac{11 times 14}{5 times 6} \ = frac{154}{30} \ = frac{77}{15} \ \ \ 9. : : 3 frac{2}{4} times 1 frac{2}{7} \ = frac{16}{4} times frac{9}{7} \ = frac{16 times 9}{4 times 7} \ = frac{144}{28} \ = frac{36}{7} \ \ 10. : : 3 frac{5}{7} times 2 frac{1}{3} \ = frac{26}{7} times frac{7}{3} \ = frac{26 times7 }{7 times 3} \ = frac{182}{21} \ = frac{26}{3}$

SEMOGA MEMBANTU
