I've attached a screenshot of the internet page where the homework questions are, which shows the problem and my answers (It says I got A right, but B and C are wrong). So I did this a few times with other tables and got the right answers, but this one is weird and the website isn't recognizing my answer. So what I did was take the 3rd value of A, divided it by the 1st value of A and got 2 as the answer. I used those rows because A changes in those rows while B stays the same. Then used the same rows to divide the 3rd row of the rate by the 1st row of the rate, and got 2 as my answer. 2 divided by 2 is 1, so the order is 1 for A. I got that one right. Then I did the same thing with B. I divided the second row of B by the 1st row of B to get 1.666666667 as my answer. Then divided the second row of the rate by the 1st row of the rate to get 1. 1 divided by 1.66666667 = 0.6. It says that's wrong. And the total order is 0.6 + 1, which is 1.6, which it says is wrong. The problem lies with the answer I got for B, but I don't know what I did wrong. Maybe it has something to do with sig figs, but my calculator gives me an exact answer of 0.6. Thanks.
