what you want to know here is whether 3/5 is smaller than 1/2,
for this, you need to bring them to the same denominator. We do this by multiplying the whole fraction by the other number's denominator:

\frac{1}{2}= \frac{1*5}{2*5}= \frac{5}{10}
which means that the first number is bigger!
so 3/5 is bigger than 1/2, which means that it is not a closer, but a further distance!
