First, you find the biggest number that goes into 15 and 40; in other words you find their greatest common factor.

(edit: here's the working out just in case:)

Factors of 15 are: 1, 3, 5, and 15.

Factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40.

In this case, it's 5. Then you divide both the numerator and denominator with that number, giving you the end result of:

\(\frac{15\div 5}{40\div 5} = \frac{3}{8}\)
