\(\left(\frac{-1}{4}+\frac{7}{33}-\frac{5}{3}\right)-\left(\frac{-5}{4}+\frac{6}{11}-\frac{48}{49}\right)=\left(\frac{-1}{4}-\frac{16}{11}\right)-\left(-\frac{31}{44}-\frac{48}{49}\right)=-\frac{1}{4}-\frac{16}{11}+\frac{31}{44}+\frac{48}{49}=-\frac{1}{49}\)
e)
\(=28\left(\frac{3}{14}-\frac{13}{21}+\frac{29}{42}\right)-8=\frac{28.2}{7}-8=8-8=0\)
3/14:1/28-13/21:1/28+29/42:1/28-8=(3/14-13/21+29/42):1/28-8=2/7:1/28-8=8-8=0
\(\frac{3}{14}:\frac{1}{28}-\frac{13}{21}:\frac{1}{28}+\frac{29}{42}:\frac{1}{28}-8\)
\(=\left(\frac{3}{14}-\frac{13}{21}+\frac{29}{42}\right):\frac{1}{28}-8\)
\(=\left(\frac{9}{42}-\frac{26}{21}+\frac{29}{42}\right):\frac{1}{28}-8\)
\(=\left(\frac{-17}{42}+\frac{29}{42}\right):\frac{1}{28}-8\)
\(=\frac{12}{42}:\frac{1}{28}-8\)
\(=\frac{2}{7}.28-8\)
\(=\frac{56}{7}-8\)
\(=8-8\)
\(=0\)
