A common denominatortor 9 and 12 is 3 and 6
This is how it is done. Let me know if you have questions...
Step-by-step explanation:

In order to know that, you need to divide it from other, if it would be perfect number then your answer will be "YES" & if they not then it will be "NO"
35/100 / 5/100
You can re-write it as:
35/100 * 100/5 = 35/5 = 7
So, they are proportional to each other,.
Hope this helps!
