Question

Вычислить (4-3/4÷1,2)×0,6

Answer 1

$(4 - frac{3}{4} div 1.2) times 0.6 = (4 - frac{3}{4} div frac{6}{5} ) times 0.6 = \ = (4 - frac{3 times 5}{4 times 6} ) times 0.6 = (4 - frac{5}{4 times 2} ) times frac{6}{10} = \ = (4 - frac{5}{8} ) times frac{3}{5} = 3 frac{3}{8} times frac{3}{5} = frac{27 times 3}{8 times 5} = frac{81}{40} = \ = 2 frac{1}{40}$
