Penjelasan dengan langkah-langkah:

$text{a}. : frac{1}{2} times frac{1}{7} : = : frac{1 times 1}{2 times 7} : = : bold{ frac{1}{14} }$

$text{b}. : frac{3}{4} times 15 = : frac{3}{4} times frac{15}{1} = frac{45}{4} : = : bold{11 frac{1}{4} }$

$small{text{c.} : frac{30}{360} times 231 = frac{1}{12} times 231 = frac{1}{12} : times : frac{231}{1} : = : frac{231}{12} : = : frac{77}{4} : = : bold{19 frac{1}{4} }}$

$text{d.} frac{1}{6} times frac{60}{90} = frac{1}{ cancel6} times frac{ cancel6}{9} = bold{ frac{1}{9} }$

$text{e.} frac{42}{3} times frac{22}{7} = frac{924}{21} = bold{44}$

$small{text{a}. : 3.2 times 6= 3 frac{2}{10} times frac{6}{1} = frac{32}{10} times frac{6}{1} = frac{192}{10} = 19 frac{2}{10} = bold{19 frac{1}{5} }}$

$text{b.} : 5 times 0.12 = frac{5}{1} times frac{12}{100} = frac{60}{100} = bold{frac{3}{5} }$

$small{text{c}. : 3.14 times 600 = frac{314}{ cancel{100}^{ : 1} } times frac{ cancel{600}^{ : 6} }{1} = frac{1884}{1} = bold{1884}}$

$smalltext{d.})0.5 times 3.2 = frac{5}{10} times frac{32}{10} = frac{160}{100} = frac{16}{10} = frac{8}{5} = bold{1 frac{3}{5} }$

$small{text{e})0.14 times 9.2 = frac{14}{100} times frac{92}{10} = frac{7}{50} times frac{46}{5} = frac{322}{250} = frac{161}{125} = 1 frac{36}{125} }$
