Answer» $\frac{4}{5} , \frac{ - 2}{3} , \frac{ - 1}{2} , \frac{ - 4}{7}$ $LCM = 210$ $\frac{4}{5} \times \frac{42}{42} = \frac{168}{210}$ $\frac{ - 2}{ 3} \times \frac{70}{70} = \frac{ - 140}{210}$ $\frac{ - 1}{2} \times \frac{105}{105} = \frac{ - 105}{210}$ $\frac{ -4 }{7} \times \frac{30}{30} = \frac{ - 120}{210}$ $SO, \: \frac{ - 140}{210} , \frac{ - 120}{210} , \frac{ - 105}{210} , \frac{168}{210}$ $\therefore \: \frac{ - 2}{3} , \frac{ - 4}{7} , \frac{ - 1}{2} , \frac{4}{5}$
