1. The problem statement, all variables and given/known data

I'm not sure how they arrived at that number, or how they "scaled it."

Thanks!

Do you know what ratio is? And how to use it in calculations?

4.03128 -> 0.02758
2.32 -> x

$$\frac {4.03128}{0.02758} = \frac {2.32}{x}$$

Actually it can be set up in several different, but equivalent ways. In the end they yield exactly the same result.

Oh, thanks. It must have been a calculator error on my part because I had the same equation set up, only I got 0.0155!!

Note to self, don't use dollar store calculators :rofl:
