Answer 2

Step-by-step explanation:

Since the denominators are not same and one is negative,

4/-9 = 4 × (-1)/(-9) × (-1) = -4/9

The L.C.M of 9,6,7 and 5 is 630

-4 × 70/9 × 70 = -280/630

3 × 105/6 × 105 = 315/630

-5 × 90/7 × 90 = -450/630

4 × 126/5 × 126 = 504/630

We know that, -450/630 < -280/630 < 315/630 < 504/630

Answer) Hence, in ascending order the numebers are -5/7, 4/-9, 3/6 and 4/5.
