0<a<b so we have a/b <1
Let's compare Quantity A / Quantity B (denoted by A/B for simplicity).
A/B=(a/5) / (b/4) = (a/5) * (4/b) = (a/b) * (4/5)
We have a/b < 1 (by the indication in the question)
4/5 = 0.8 <1
so the product is below 1.
Thus A/B < 1 which means B is greater.
So we should choose answer B.
