Question

вычислите:а)- 2\3+1\6 б)7\9-1\6 в) - 3\8-1\2

Answer 1

а) -2/3 + 1/6 = -4/6 + 1/6 = - 3/6 = - 1/2
б) 7/9 - 1/6 = 14/18 - 3/18 =11/18
в) -3/8 - 1/2 = -3/8 - 4/8 = - 7/8

Answer 2

$- \frac{2}{3} + \frac{1}{6} = - \frac{1}{2}$

(вложение)

$\frac{7}{9} - \frac{1}{6} = \frac{11}{18}$

(вложение)

$- \frac{3}{8} - \frac{1}{2} = - \frac{7}{8}$
