Question 1023103: http://prntscr.com/aajkcx
I've posted this before, but I think the tutor got the wrong idea of what I was asking so I'll try to be more clear.I set mine up 47/x=82.8/92 but I get the wrong answer. But when it's setup as 47/x=82/73.8 it gives you the right answer. So, I tried to setup as 47/x=92/73.8 it gives the wrong answer. I would like someone to explain why when you setup ONE way it gives you the right answer and why when it's setup the OTHER ways it gives you the wrong answer.

When you use the correct proportion, you get the correct answer.

That is all.
