Jawaban:

$1 : : : frac{8}{25}$

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

$3. : : : 1 frac{9}{32}$

$4. : : : 3 frac{17}{20}$

$5 : : : 9 frac{1}{5}$

Penjelasan dengan langkah-langkah:

$1. : : : frac{8}{20} times frac{12}{15} = frac{8 times 12}{20 times 15} = frac{96}{300} = frac{8}{25}$

$2. : : : frac{16}{32} times frac{4}{9} = frac{16 times 4}{32 times 9} = frac{64}{288} = frac{2}{9}$

$3. : : : 2 frac{11}{15} times frac{15}{32} = frac{(15 times 2) + 11}{15} times frac{15}{32} = frac{41}{15} times frac{15}{32} \ = frac{41 times 15}{15 times 32} = frac{615}{480} = 1 frac{135}{480} = 1 frac{9}{32}$

$4. : : : 4 frac{13}{16} times frac{32}{40} = frac{(16 times 4) + 13}{16} times frac{32}{40} = frac{77}{16} times frac{32}{40} \ = frac{77 times 32}{16 times 40} = frac{2464}{640} = 3 frac{544}{640} = 3 frac{17}{20}$

$5. : : 3 frac{5}{6} times 2 frac{2}{5} = frac{(6 times 3) + 5}{6} times frac{(5 times 2) + 2}{5} = frac{23}{6} times frac{12}{5} \ = frac{23 times 12}{6 times 5} = frac{276}{30} = 9 frac{6}{30} = 9 frac{1}{5}$
