first , we have to find the LCM(LEAST COMMON MULTIPLE) of the denominators.
LCM = 7×2×5 = 70
Next change the denominator as well as numerators with reaching all the denominators 70
-12/7 = -12×10/7×10 = -120/70
15/2 = 15×35/2×35 = 525/70
8/7 = 8×10/7×10 = 80/70
12/5 = 12×14/5×14 = 168/70
Now, all the denominators are same
so we can easily das arrange them in a number line........
