(377/-231-123/89+34/791)*(1/6-1/8-1/24)
= (377/-231-123/89+34/791)*[4/24+(-3/24)+(-1/24)]
= (377/-231-123/89+34/791)* 0
= 0
\(\left(\frac{377}{-231}-\frac{123}{89}+\frac{34}{791}\right).\left(\frac{1}{6}-\frac{1}{8}-\frac{1}{24}\right)\)
\(=\left(\frac{337}{-231}-\frac{123}{89}+\frac{34}{791}\right).\left(\frac{4-3-1}{24}\right)\)
\(=\left(\frac{337}{-231}-\frac{123}{89}+\frac{34}{791}\right).0\)
\(=0\)
