If you're looking for the simplified version of the fraction, you have to factor both numerator and denominator.
The numerator is actually already a prime number, so we're good
The denominator factors as 
So, a 3 appears in both numerator and denominator. We can simplify it:

If you want to compute the approximated value of this fraction, simply plug these values into some calculator to get

3/5q = 1 Given
(3/5) 3/5q = 1(3/5) Multiply each side by 3/5 (Mult. Prop. of Equal)
q = 3/5 Simplify
