Question

if p/q =6/5 then find the value of ratio 5p-6q/5p+6q​

Answer 1

$The \: value \: of \: \frac{5p- 6q}{3p +4q}$

Given:

$\frac{p}{q}$

$= \frac{6}{5}$

=1.2

To find:

$Find \: the \: value \: of \: \frac{5p- 6q}{3p +4q}$

Explanation:

$\frac{p}{q}$

$= \frac{6}{5}$

=1.2 ⇒ p= 1.2q

Put this value in the equation whose value should be calculated

$\frac{5p- 6q}{3p +4q}$$= \frac{5\times 1.2q - 6q}{3\times 1.2 +4q}$

$\frac{5p- 6q}{3p +4q}$=$\frac{6q- 6q}{3.6q +4q}$

$\frac{5p- 6q}{3p +4q}$=$\frac{0}{7.6q}$

$\frac{5p- 6q}{3p +4q}$=o

$Alternative \: method, \: \frac{p}{q}$=$\frac{6}{5}$

put P=6 and q=5 we can get a same value that is answer should be zero.

$\frac{5p- 6q}{3p +4q}=$$\frac{5\times 6- 6\times 5}{3\times 6 +4\times 5}= 0$

You can use which ever method the answer should be same I think second method should be little bit easy.

$The \: value \: of \: \frac{5p- 6q}{3p +4q} = 0$
