- These ratios are proportional to each other
Write two ratios:
[tex]\dfrac{117\hspace{3}dollars}{1\hspace{3}week}[/tex]
[tex]\dfrac{234\hspace{3}dollars}{2\hspace{3}weeks}[/tex]
Set them equal to each other:
[tex]\dfrac{117\hspace{3}dollars}{1\hspace{3}week}= \dfrac{234\hspace{3}dollars}{2\hspace{3}weeks}[/tex]
Answer
[tex]\dfrac{117\hspace{3}dollars}{1\hspace{3}week}= \dfrac{234\hspace{3}dollars}{2\hspace{3}weeks}[/tex]
