Answer 2

Step-by-step explanation:

Since the denominator is not same then,

The L.C.M of 9 and 7 is 63

2 × 7/9 × 7 = 14/63

4 × 9/7 × 9 = 36/63

Now if we add them,

14/63 + 36/63 = 50/63

Now if we substract them

14/63 - 36/63 = -22/63

Now if we divide them then,

(50/63 ÷ (-22/63)) = 50/63 × 63/-22 = 3150/-1386

=> 3150/-1386 = 1575/-693 = 525/-231 = 175/-77

Answer) 175/-77
