Question

if a/b=8/3,find 4a+5b/4a-5b

Answer 1

Answer:

Step-by-step explanation:

According to the question.

A=8

B=3

Find 4a+5b/4a-5b

4a/4a+5b-5b=1+0

Answer=1

Answer 2

$\frac{4a + 5b}{4a - 5b}$
On applying componendo and dividendo,

$\frac{4a + 5b + 4a - 5b}{4a + 5b - 4a + 5b}$
On solving,
we get,

$\frac{8a}{10b}$
And since, a/b = 8/3

Therefore,

$\frac{8}{10} \times \frac{8}{3}$
So,

$\frac{64}{30}$
