Maths grade average question
Question asked by: julianna
Asked on: 18 Sep 2010
Add those 9 up and then divide by nine to find the average of those nine.
Then work out what you need to add such that when you divide by 10 you get 71.
There you go, that's the method for you but we've not done all the work so that you can still do a little learning with regard to working this out and not just getting the answer given straight to you - perfect!
