Answer:
[tex]Ratio\ of\ width\ to\ the\ length=\frac{15}{41}[/tex]
Step-by-step explanation:
[tex]Ratio\ of\ width\ to\ the\ length=\frac{width}{length}\\\\Here\ length=123\ mm\\\\Width=45\ mm\\\\Ratio\ of\ width\ to\ the\ length=\frac{45}{123}\\\\Ratio\ of\ width\ to\ the\ length=\frac{3\times15}{3\times 41}\\\\Divide\ numerator\ and\ denominator\ by 3\\\\Ratio\ of\ width\ to\ the\ length=\frac{15}{41}[/tex]
