Question

what is the value of p+q/p-q , if p/q =7 ?

Answer 1

p/q = 7
⇒ p = 7q
p+q/p-q
= 7q + q / 7q - q
= 8q/6q
=4/3

Answer 2

Answer:

value of $\frac{p+q}{p-q}$ =$\frac{4}{3}$

Explanation:

Given $\frac{p}{q}=7$---(1)

Now ,

value of $\frac{p+q}{p-q}$

/* Divide numerator and denominator by q, we get

= $\frac{\frac{p+q}{q}}{\frac{p-q}{q}}$

= $\frac{\frac{p}{q}+\frac{q}{q}}{\frac{p}{q}-\frac{q}{q}}$

= $\frac{\frac{p}{q}+1}{\frac{p}{q}-1}$

= $\frac{7+1}{7-1}$

/* From (1) */

= $\frac{8}{6}$

= $\frac{4}{3}$

Therefore,

value of $\frac{p+q}{p-q}$ =$\frac{4}{3}$
