Arithmetic refreshers needed

Both from today:

The bag of Sun Chips proclaimed that they contain "30% less fat than regular potato chips." The copy writer went on to explain that potato chips have 10g fat/oz., and Sun Chips have 6g fat/oz. Umm, I'm pretty sure that's 40% less fat.

A Washington Post article on the state of mental health care in Virginia, in the wake of the tragedy involving the state Senator's family, says that the commonwealth "has just 17.6 beds per 10,000 people, 40 percent of a target of 50 beds per 10,000."  Umm, no, but I wouldn't have quibbled with them had they said 35 percent.

I suppose these are both "rounding errors"?
