2. (12 1/4 + 7 1/2) : 9 4/5
3. (6 2/5 + 4 1/5) – (4 1/2 x 2 2/3)

Ubahlah menjadi pecahan campuran

Jawaban:

$1)(2 frac{1}{2} times 4 frac{1}{3} times 6 frac{2}{5} \ =( frac{5}{2} times frac{13}{3}) times frac{32}{5} \ = frac{65}{6} times frac{32}{5} \ = frac{2.080}{30} \ = frac{208}{3} \ = 69 frac{1}{3}$

$2)(12 frac{1}{4} times 7 frac{1}{2}) div 9 frac{4}{5} \ (frac{25}{4} times frac{15}{2} ) div frac{49}{5} \ = frac{375}{8} times frac{5}{49} \ = frac{1.875}{392} \ =4 frac{307}{392}$

$3)(6 frac{2}{5} times 4 frac{1}{5} ) - (4 frac{1}{2} times 2 frac{2}{3} ) \ = ( frac{32}{5} times frac{21}{5} ) - ( frac{9}{2} times frac{8}{3}) \ = frac{672}{25} - frac{72}{6} \ = frac{4.032}{150} - frac{1.800}{150} \ = frac{2.232}{150} \ = 14 frac{132}{150}$
