When simplified all of them equal 3/1. They are asking you to just chose 4 of them. Hope that helps!
The only point which is a solution is C
Its 1/5,
35/100 - 15/100 = 20/100
for 20, 40, 60, 80, 100
1, 2, 3, 4, 5
so 20/100 = 1/5
b) u gotta each R point w p & q and see which one would give u a right triangle, which is b
