Question

решите дробь (2 5/6+2 2/9):3 1/4-2/9

Answer 1

$(2 frac{5}{6} + 2 frac{2}{9} ) div 3 frac{1}{4} - frac{2}{9} = frac{28}{9 } - frac{2}{9} = frac{26}{9} \ 2 frac{5}{6} + 2 frac{2}{9} = frac{17}{6} + frac{20}{9} = frac{51 + 40}{18} = frac{91}{18} \ frac{91}{18} div 3 frac{1}{4} = frac{91 times 4}{18 times 13} = frac{7 times 4}{9} = frac{28}{9}$
