Penjelasan dengan langkah-langkah:

$1. : : (1 frac{7}{8} times 2 frac{5}{6} ) + (1 frac{7}{8} div 5 frac{1}{6} ) \ \ (frac{15}{8} times frac{17}{6} ) + ( frac{15}{8} times frac{6}{31} ) \ \ ( frac{5}{8} times frac{17}{2} ) + (frac{15}{4} times frac{3}{31} ) \ \ frac{85}{16} + frac{45}{124} = frac{2.635 + 180}{496} = frac{2.815}{496} = 5 frac{15}{496}$

$2. : : (1 frac{7}{8} div 2 frac{5}{6} ) - (1 frac{7}{8} times 5 frac{1}{6} ) \ \ (frac{15}{8} times frac{6}{17} ) - ( frac{15}{8} times frac{31}{6} ) \ \ (frac{15}{4} times frac{3}{17} ) - ( frac{5}{8} times frac{31}{2} ) \ \ frac{45}{68} - frac{155}{16} = frac{180 - 2.635}{272} = - frac{2.445}{272} = - 8 frac{269}{272}$
