Question

ifa/b=7/3 then find the values of the following ratios. (ii) 2a²+3b²/2a²-3b²​

Answer 1

Answer:

125/71

Step-by-step explanation:

a/b=7/3

3a=7b

a=7b/3

2a²+3b²/2a²-3b²

{2(7b/3)²+3b²}/{2(7b/3)²-3b²}

{2(49b²/9)+3b²}/{2(49b²/9)-3b²}

{98b²/9+3b²}/{98b²/9-3b²}

{(98b²+27b²)/9}/{(98b²-27b²)/9}

{(98b²+27b²)/(98b²-27b²)}

{(125b²)/(71b²)}

{(125)/(71)}

125/71
