500 divided by 750 ??
OpenStudy (anonymous):
yes and 4 by 25
OpenStudy (anonymous):
4 divided by 25 is 0.16
OpenStudy (anonymous):
and 500 divided by 750 is 0.6666666666666667

Okay so I think the answer is A. Do you agree with me? Becuase if you look, 4 and 25, Their factors would be 2 for 4 and 5 for 25.
