OK, less than a quarter is probably an exaggeration, but for instance, a history major at UIUC requires 36 credit-hours: http://www.history.illinois.edu/undergraduate/major/

An astronomy major at UIUC requires less than a quarter of classes in astronomy (26 credit-hours) but does have math and physics requirements as well: Astronomy Major | Department of Astronomy | UIUC

36 credits is 30% of the degree.

For astronomy, the total number of credits (including the math and physics) is 48-49, or 40% of the degree.
