Penjelasan dengan langkah-langkah:

$2). : 50% div frac{1}{2} times 2.8 \ = frac{50}{100} div ( frac{1}{2} times frac{14}{5} ) = frac{1}{2} div frac{14}{10} \ = frac{1}{2} div frac{7}{5} = frac{1}{2} times frac{5}{7} = frac{5}{14} \ \ 3). : 5 frac{1}{4} div 1 frac{1}{2} times 2.5 \ = frac{21}{4} div ( frac{3}{2} times frac{5}{2} ) = frac{21}{4} div frac{15}{4} \ = frac{21}{4} times frac{4}{15} = frac{84}{60} = frac{7}{5} \ \ 4). : 3 frac{1}{5} times frac{3}{8} div 0.6 = ( frac{16}{5} times frac{3}{8} ) div frac{3}{5} \ = frac{48}{40} times frac{5}{3} = frac{6}{5} times frac{5}{3} = frac{30}{15} = 2$
