Solution

Given rational numbers are

-34,5-12,-716,9-24

First of all, we express each of the given numbers with a positive denominator.

We have 5-12=5×(-1)-12×(-1)=-512

9-24=9×(-1)-24×(-1)=-924

Therefore, given rational numbers are -34,-512,-716,-924

Now, LCM(4,12,16,24)=48

Thus,

-34=-3×124×12=-3648-512=-5×412×4=-2048-716=-7×316×3=-2148-924=-9×224×2=-1848

Since, 3648>2148>2048>1648

Therefore, -3648<-2148<-2048<-1848-34<-716<-512<-924

Hence, the given rational numbers in their ascending orders are

-34,-716,5-12,9-24
