Answer:
the answer will be the second graph
Explanation:
in the other graphs, the proportions are not equal
for example, in the top graph, your first and second proportions simplify to 1/5; but your third and fourth simplify to 1/4
in the third graph, your first and second simplify to 1/3 and your third and fourth simplify to 1/4
however, in the second graph, the proportions simplify to 1/3 throughout
