Thực hiện phép tính một cách hợp lí: g) 17/8 : − 11/3 + 31/8 . − 3/11 + 4/11 .

g) \(\frac{{17}}{8}:\frac{{ - 11}}{3} + \frac{{31}}{8} \cdot \frac{{ - 3}}{{11}} + \frac{4}{{11}}\)

\( = \frac{{17}}{8} \cdot \frac{{ - 3}}{{11}} + \frac{{31}}{8} \cdot \frac{{ - 3}}{{11}} + \frac{4}{{11}}\)

\( = \frac{{ - 3}}{{11}} \cdot \left( {\frac{{17}}{8} + \frac{{31}}{8}} \right) + \frac{4}{{11}}\)

\( = \frac{{ - 3}}{{11}} \cdot \frac{{48}}{8} + \frac{4}{{11}}\)

\( = \frac{{ - 3}}{{11}} \cdot 6 + \frac{4}{{11}}\)

\( = \frac{{ - 18}}{{11}} + \frac{4}{{11}} = \frac{{ - 14}}{{11}}.\)
