We will have that the number that makes the ratio equivalent will be:
[tex]22\colon9[/tex]We find this as follows:
We divide the equivalent ratio, that is:
[tex]\frac{36}{9}=4[/tex]So, now we divide the first one by that:
[tex]\frac{88}{4}=22[/tex]Then, we can see that:
[tex]\frac{88}{36}=\frac{22}{9}\Rightarrow\begin{cases}88\colon36=22\colon9\end{cases}[/tex]
