Question

Решите пример ( 4 целых 5/12 + 1 целая 3/4) : (6 целых 2/15 -1 целая 1/5)

Answer 1

$(4 frac{5}{12} + 1 frac{3}{4} ) div (6 frac{2}{15} - 1 frac{1}{5} ) = (4 frac{5}{12} + 1 frac{9}{12} ) div (6 frac{2}{15} - 1 frac{3}{15} ) = \ = 5 frac{14}{12} div (5 frac{17}{15} - 1 frac{3}{15} ) = 5 frac{7}{6} div 4 frac{14}{15} = frac{37}{6} times frac{15}{74} = frac{15}{6 times 2} = frac{15}{12} = \ = 1 frac{3}{12} = 1 frac{1}{4} = 1.25$
