HI!!
OpenStudy (misty1212):
it is the ratio of the number of blue marbles to the total number of marbles
OpenStudy (anonymous):
4/12=1/3
OpenStudy (anonymous):
Okay thank you both
OpenStudy (anonymous):
I shouldn't have gave you a direct answer. Sorry. Add all the numbers up 3+5+4. Then find how many blue. 4/12, then reduce. Your final answer is 1/3
