Answer:
[tex]\frac{3}{8}[/tex]
Step-by-step explanation:
since [tex]\frac{5}{8}[/tex] has been completed
the remaining would be :
[tex]\frac{8}{8} -\frac{5}{8}[/tex]
since denominators are the same
= [tex]\frac{8 - 5}{8} \\\\[/tex]
= [tex]\frac{3}{8}[/tex]
the fraction of the race that is remaining is 3/8
