To answer this question we will use the following property of ratios:
[tex]ab:cb=a:c.[/tex]We know that:
[tex]1week=7days.[/tex]Therefore we can rewrite the given ratio as follows:
[tex]35\text{ days to }8*7\text{ days.}[/tex]Simplifying the above ratio we get:
[tex]35:8*7.[/tex]Now, notice that 35=5*7, then:
[tex]35:8*7=5*7:8*7=5:8.[/tex]The above ratio as a fraction is:
[tex]\frac{5}{8}.[/tex]Answer:
[tex]\frac{5}{8}.[/tex]
