Last one! Please help! South America's total population was 515,000,000 and the world's total population was 6,279,000,000. What percentage was South America rounded to the nearest tenth?

  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.

  Chopsticks -- you forgot to convert your answer to a percent.

  8%

  Oh. .1 = 10%

  
  

• Math - Bella, Sunday, February 22, 2009 at 10:14pm

  shouldn't you convert .08?

  
  

• Math - Ms. Sue, Sunday, February 22, 2009 at 10:14pm

  The problem states to the nearest tenth. 8.2%

  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.
