515,000,000/6,279,000,000
Dont get intimidated by large numbers. Plug that into a calculator to find the answer. I don't know if that number fits into a calculator to be honest.

Oh dang sorry haha. I converted it to the nearest tenth when I saw .08, I forgot about the percentage in tenths.

Sounds as if Chopsticks needs to leave the math helping to the math tutors who don't forget these things ... so that other students don't go away with the wrong process and/or answers.
