Well that is wrong. that is not an answer choice.
OpenStudy (jennyrlz):
@lana_mk is correct
OpenStudy (lana_mk):
@jennyrlz thanks :)
OpenStudy (jennyrlz):
how you do it is add all the marbles together (50) and then divide it the red ones by this number
18/50
OpenStudy (jennyrlz):
np :)

C
OpenStudy (lana_mk):
It would be 9/25 then.
OpenStudy (rainbow_rocks03):
How can you reduce 18:50 into 9/25 ?
OpenStudy (jennyrlz):
divide both sides by 2
OpenStudy (lana_mk):
they both can be divided by 2
