Question

If ax+b cx+d = p / q then q(ax+b) = p( cx+d) this process is called --------

Answer 1

/* There is a mistake in the question . It may be like this */

$If \: \frac{ax+b}{cx+d} = \frac{p}{q} \: then \\q(ax+b) = p(cx+d) \\this \: process \: is \: called \\\underline { \pink { proportion }}$

$We \:know \:that ,$

$\boxed { \pink {If \: a : b = c : d \: then \: ad = bc }}$

$\blue { ( Product \:of \: extremes = product \:means ) }$

Answer 2

Answer:

* There is a mistake in the question . It may be like this */

$$\begin{lgathered}If \: \frac{ax+b}{cx+d} = \frac{p}{q} \: then \\q(ax+b) = p(cx+d) \\this \: process \: is \: called \\\underline { \pink { proportion }}\end{lgathered}$$

$$We \:know \:that ,$$

$$\boxed { \pink {If \: a : b = c : d \: then \: ad = bc }}$$

$$\blue { ( Product \:of \: extremes = product \:means ) }$$
