Well.. so many folks caught a cold
so many off that total, recovered,
keep in mind that, the folks who recovered
are just a fraction of the ones who were
sick

so... simply subtract the "recovered" polynomial,
from the "caugh cold" polynomial, namely
\begin{cases}
8t-5t^2+t^3\impliedby &\textit{caught a cold}\\
\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\\

\cfrac{5-t^2+1}{5t^3}\impliedby &recovered
\end{cases}
\\ \quad \\\
[8t-5t^2+t^3]-\left[ \cfrac{5-t^2+1}{5t^3} \right]\implies \textit{still sick}

2 dogs/ 3 cats and 10 dogs/ 15 cats are an example of

b. Equivalent ratios
__________________________

\frac{10 \: dogs}{15 \: cats}  =  \frac{5 \times 2 \: dogs}{ 5 \times 3 \: cats}  =  \frac{2 \: dogs}{3 \: cats}  \\

We can see that they are equivalent ratios.
