You can put this solution on YOUR website!
It should mean 9 is to 3 as 49 is to some unknown number!

This is indeed a proportion.

You can set it up like this:

9%2F3=49%2Fx given

9%2Ax=49%2A3 cross multiplication

9x=147 simplify

x=147%2F9 simplify

x=49%2F3 answer

So, we now have 9:3::49:(49/3)

or 9:3::49:(16 and 1/3)

I believe the most proper answer for the missing number would be 49/3

I hope this helps!
