Example of problem for the student's blog

Hello students! Here you've got an example of what you can do to show here, on the blog.

I've just found some news about environment and percentages (%). This is interesting:


It says that the 79 % of the spanish population breathes polluted air. And it adds that it means that it is 4 out of 5. Is it the same?

Yes, approximately!! 79/100 = 4/5

I hope this can be a source of ideas for all of you students!
