Bad at Math: 0.166666667 is what percent of 128

I put 0.166666667 oz of salt in 128 oz of water. What percentage of salt is in the water? What equation did you use? I may not even be asking the question correctly.
Thanks!

It's the fraction times 100. (0.166666667 / 1280) * 100

You get an answer saying that 0.13% of the solution is salt.

I don't mean to be a wiseass, but the "percent of salt in the water" is 100%, or all of the 1/6 oz of salt =Þ

As for what you're obviously trying to ask, the concentration of salt in the water is (.16666... / 128) * 100, or ~0.13021%
