Answer:

272/1071

Explanation:

First we will Take lcm and match the denominators:

15/7 × 9/9 = 135/63

-8/9 × 7/7 = -56/63

12/17 × 3/3 = 36/51

-5/3 × 17/17 = -85/51

Hence:

135 - 56 / 63 + 36 - 85 /51

79/63 + (-49/51)

Lcm : 1071

79 /63 × 17/17 = 1343/1071

-49/51 × 21/21 = - 1029/1071

1343/1071 - 1029/1071

= 272/1071
