7.6 A European engineer works for an American automobile man- ufacturer. She measures the diameter of an automobile drive shaft using a micrometer, an accurate measuring device. The microme- ter reads 2.0573. When she records the reading, she instinctively writes "2.0573 cm." An American engineer is checking the European's work and determines there is a mistake; the microme- ter measures inches, not centimeters. What is the fractional eror and percentage error of the diameter recorded by the European engineer?
