Answer 1

Explicație pas cu pas:

g)

$1 - \frac{5}{14} = \frac{14}{14} -\frac{5}{14} = \frac{14 - 5}{14} = \frac{9}{14}$

h)

$- 4 \frac{2}{9} + \frac{1}{3} + 2\frac{1}{6} = - \frac{4 \times 9 + 2}{9} + \frac{1}{3} + \frac{2 \times 6 + 1}{6} \\ = - \frac{38}{9} + \frac{1}{3} + \frac{13}{6} = - \frac{38 \times 2}{9 \times 2} + \frac{1 \times 6}{3 \times 6} + \frac{13 \times 3}{6 \times 3} \\ = \frac{ - 76 + 6 + 39}{18} = - \frac{31}{18}$
