Jawaban:

$1.) : : : frac{1}{10} : : : atau : : : 0.1$

$2.) : : : frac{5}{9}$

$3.) : : : frac{4}{7}$

Penjelasan dengan langkah-langkah:

$1.) : : : frac{4}{5} times frac{2}{10} div frac{8}{5} = frac{1}{10} : : : atau : : : 0.1$

Langkah-langkah:

$= frac{4}{5} times frac{2}{10} div frac{8}{5} \ \ = frac{4}{5} times frac{2 div 2}{10 div 2} times frac{5}{8} \ \ = frac{4}{5} times frac{1}{5} times frac{5}{8} \ \ = frac{4}{1} times frac{1}{5} times frac{1}{8} \ \ = frac{1}{5} times frac{1}{2} \ \ = frac{1}{10} : : : atau : : : 0.1$

$2.) : : : frac{2}{6} div frac{9}{5} div frac{4}{12} = frac{5}{9}$

Langkah-langkah:

$= frac{2}{6} div frac{9}{5} div frac{4}{12} \ \ = frac{2}{6} times frac{5}{9} times frac{12}{4} \ \ = frac{2 div 2}{6 div 2} times frac{5}{9} times frac{12 div 4}{4 div 4} \ \ = frac{1}{3} times frac{5}{9} times frac{3}{1} \ \ = frac{1}{1} times frac{5}{9} times frac{1}{1} \ \ = frac{5}{9}$

$3.) : : : frac{2}{7} div frac{1}{6} times frac{2}{6} = frac{4}{7}$

Langkah-langkah:

$= frac{2}{7} div frac{1}{6} times frac{2}{6} \ \ = frac{2}{7} times frac{6}{1} times frac{2}{6} \ \ = frac{2}{7} times frac{1}{1} times frac{2}{1} \ \ = frac{4}{7}$
