Question

3 4/9 - 2 5/6 = ответ?

Answer 1

Ответ:

$\frac{11}{18}$

Пошаговое объяснение:

$3\frac{4}{9}-2\frac{5}{6}=3\frac{4*2}{9*2}-2\frac{5*3}{6*3}=3\frac{8}{18}-2\frac{15}{18}=(3-1)+\frac{8+18}{18}-2\frac{15}{18}=2\frac{26}{18}-2\frac{15}{18}=\frac{11}{18}$

Answer 2

$3 \frac{4}{9} - 2 \frac{5}{6} = \frac{3 \times 9 + 4}{9} - \frac{2 \times 6 + 5}{6} = \frac{31}{9} - \frac{17}{6} = \frac{31 \times 2}{9\times 2} - \frac{17 \times 3}{6 \times 3} = \frac{62}{18} - \frac{51}{18} = \frac{62 - 51}{18} = \frac{11}{18}$
