Just divide it

OpenStudy (anonymous):

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.

OpenStudy (anonymous):

yes I agree but are u 100% sure?

OpenStudy (anonymous):

OpenStudy (anonymous):
