Given a model in which some boxes are given.
Here, 1/2 is represented by 3 boxes and 2/3 is represented by 4 boxes. Thus, the model represents that 3/4 of 2/3 bar is equal to 1/2.
So, the mathematical representation of the model is:
![(1)/(2)=(3)/(4)*(2)/(3)](https://img.qammunity.org/2023/formulas/mathematics/college/7ok8tsx5gz7fsorotghe6t2cc59yc0o8vm.png)
If we divide both the sides by 2/3, we get:
![\begin{gathered} (1)/(2)/(2)/(3)=(3)/(4)*(2)/(3)/(2)/(3) \\ (1)/(2)/(2)/(3)=(3)/(4) \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/dsqucaozmtrlv5c1ifzbc6rqvjajquy67d.png)
