Question

solve the following question step by step​

Answer 1

Answer:

125/71

Step-by-step explanation:

a/b = 7/3

=> 3a = 7b

=> 9a² = 49b²

=> a² = 49/9 b²

=> 2a² = 98/9 b²

Now,

2a²+3b²/2a²-3b²

= (98/9b² + 3b²)/ (98/9b² - 3b²)

= b²(98/9 + 3)/b²(98/9-3)

= (98+27)/(98-27)

= 125/71

= 1.76 (approx)

Answer 2

Answer:

125/71
