Question

if p:q::r:s are in proportion, then can we say p×r=q×s .justify your answer
​

Answer 1

Answer:

this statement is false.

Step-by-step explanation:

p:q can also be written as p/q

r:s can also be written as r/s

equation of proportionality can also be written as

p/q = r/s

$\frac{p}{q} = \frac{r}{s}$

cross multiply

p×s = r×q

or

p/r = q/s

so given p×r = q×s can't be true.
