ANSWER
[tex]1\colon1\colon4[/tex]EXPLANATION
We want to find the ratio of 2 weeks to 14 days to 8 weeks.
To do this, we first have to put all three terms in the same unit. Let us put all the terms in days.
To convert from weeks to days, multiply the weeks by 7:
[tex]\begin{gathered} 2w=2\cdot7=14d \\ 8w=8\cdot7=56d \end{gathered}[/tex]Therefore, the ratio becomes:
[tex]14days\colon14days\colon56\text{days}[/tex]Now, put it in the lowest terms by dividing through by 14. That is:
[tex]1\colon1\colon4[/tex]That is the answer.
