"Our research found 60% of customers don't understand percentages so it's extremely challenging to shop in the store in an informed manner," says Beth Flower, nutrition and health manager at Sainsbury's."

My foster brother got very confused by percentages due to bad teaching, I wouldn't be surprised if it happens to lots of other people. To whit:

"We're going to learn about 10% first, because that's easy. To find 10% you divide by 10"

He gets all the 10% questions right, and then follows the pattern he has been taught, dividing by 20 to get 20%, by 40 to get 40%, etc...

What I found more depressing was that the teacher had just marked his answers wrong, instead of noticing what the problem was.

That's an almost unbelievably stupid way to teach...poor kid!
