Question

are 3,5,15,9 in proportion? if we change their order, can we think of proportional pairs? write as many proportionality statements as you can for the above example. ?

Answer 1

hiii friend...
.
.
yes it is in propotion....
because....
1=4
2=3 then,
3\9=5/15then the answer is proved....

Answer 2

Answer: The answer is given below.

Step-by-step explanation:  Given that 3, 5, 15 and 9 are in proportion. We are to write the maximum possible proportionality statements, if on changing the order, we can think of proportional pairs.

The possible proportionality statements are

$\dfrac{3}{5}=\dfrac{9}{15},\\\\\\\dfrac{5}{3}=\dfrac{15}{9},\\\\\\\dfrac{3}{9}=\dfrac{5}{15},\\\\\\\dfrac{9}{3}=\dfrac{15}{5}.$
