Am I confused here? The BBC says, 'One in five oppose GM' and "Britons oppose the introduction of genetically modified crops by five to one".

I know I didn't do as well as I'd hoped in the IQ test and maths never was my strong suite, but this seems not quite right to me somehow. Shouldn't that be 5 out of 6 oppose GM?

[Update: they fixed the headline. Good bloody thing. I thought I was losing my mind.]
