Question

Are the following numbers in proportion?
(a) 9, 12, 18, 24
​

Answer 1

Step-by-step explanation:

First we write in proportion

9:12::18:24

We multiple the no. in cross pending

9/12=18/24

9×28=12×18

252=216

so the no. is not in proportion

Answer 2

No they are not in proportion this is the answer
