5.macy measured the mass of a 69.3 g mouse at 70.0 g.
eli measured the mass of a 3867 kg elephant at 3900 kilograms.

macy's error was 70-69.3 = 0.7 g-- about half the mass of a paperclip.

a. what was eli's error?

b. name an object of this approximate mass.

c. accuracy can be defined in terms of percent error. who was more accurate, macy or eli? justify your answer with mathematics.
