Answer :
[tex]\frac{20}{15}\\\\GCF(15;\ 20)=5\\\\divide\ a\ numerator\ and\ a\ demoninator\ by\ 5\\\\\frac{20}{15}=\frac{4}{3}=1\frac{1}{3}[/tex]

It can be further simplified
fractions can be simplified by finding the highest common factor for both 15 and 20 and dividing the numerator by the highest common factor
factors for 15 and 20 are as follows
15 - 1,3,5,15
20,-,1,2,4,5,10,20

so divide both by 5
[tex] \frac{20/5}{15/5} = \frac{x4}{3} [/tex]
this can be written as a proper fraction
in 4/3 there's one whole number and 1/3 remaining
