3 /8 dikali 2 1/5 – 1/2 : 1 1/4

Jawaban:

3/8 X 2 1/5 – 1/2 : 1 1/4 = 17 /40 = 0,425

$(frac{3}{8} times 2 frac{1}{5}) - (frac{1}{2} div 1 frac{1}{4}) \ = (frac{3}{8} times frac{11}{5} ) - ( frac{1}{2} div frac{5}{4} ) \ = (frac{3}{8} times frac{11}{5} ) - ( frac{1}{2} times frac{4}{5} ) \ = frac{33}{40} - frac{4}{10} \ = frac{33}{40} - frac{16}{40} \ = frac{17}{40}$
