Answer:
[tex]\frac{3}{4}[/tex]
Step-by-step explanation:
No. of remaining days = [tex]\frac{7}{8}[/tex] - [tex]\frac{1}{8}[/tex]
If the denominators are the same, you can directly do the working for the numerators while leaving the denominator alone.
[tex]\frac{7}{8}[/tex] - [tex]\frac{1}{8}[/tex] = [tex]\frac{6}{8}[/tex]
6 and 8 both have a common factor of 2, so we can further simplify this fraction.
[tex]\frac{6}{8}[/tex] = [tex]\frac{3}{4}[/tex]
Thus, he must drive for [tex]\frac{3}{4}[/tex] more days.
