Five percent VS The five percent.
Which one is correct and why?
Because i.e. this page exists http://www.thetwopercent.com/ or the famous slogan ;) "we are the 99%.".
However, on the official apple website: http://www.apple.com/environment/renewable-energy/
is this without the article:
By the end of 2012, we’ll meet the energy needs of our Maiden, North Carolina, data center using entirely renewable sources. To achieve this, we’re building our own facilities that will provide over 60 percent of the clean power we need. It’s another example of Apple’s commitment to designing for energy efficiency — from the ground up.
Unfortunately there is some bad news as well: Only about 22 percent of the teachers said that they have access to the right level of technology. Nearly two-thirds — about 63 percent — explained that budget issues are the "biggest barrier to accessing tech in the classroom." (In low-income communities, that statistic jumped to 70 percent.)
And these are the well known websites apple and nbc. I do not understand at all.
Are both ways correct?
When should I use the definite article and when I shouldn't?
