amee, ben, carly, and darrien are friends. darrien has no money. amee gives darrien 1/4 of her money. ben gives darrien 1/5 of his money. carly gives darrien 1/3 of her money. each person gave darrien the same amount. what fraction of the groups total money does darrien have at the end?
clearly the ratio of the holdings obeyed
a:b:c = 4:5:3
since there were 12 total parts, and
d ended up with 3 of them,
3/12 = 1/4
