Question

Are 3,5,15,9 in proportion ? If we change theri order can we think of proportional pairs write as many porportionality statement as you can for the above example

Answer 1

Answer:

Yes it is a proportion.

Step-by-step explanation:

Given: 3, 5, 15 and 9 are in proportion.

To find : Are 3,5,15,9 in proportion ? If we change their order can we think of proportional pairs write as many proportionality statement as you can for the above example?

Solution :

Yes it is a 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

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

Therefore, Yes it is a proportion.
