Question

Выполните действие -7/18-5/12
-2 3/10+(-3 1/8) сроочно

Answer 1

1).
$\frac{-7}{18} - \frac{5}{12} = \frac{-14}{36} - \frac{15}{36} = \frac{-14-15}{36} = -\frac{29}{36}$

2).
$-2 \frac{3}{10} +(-3 \frac{1}{8} )=-2 \frac{3}{10}-3 \frac{1}{8}= -2 \frac{24}{80} -3 \frac{10}{80} =-5 \frac{14}{80} =-5 \frac{7}{40}$
