Question

А 10 0 B В 1) Which one of these shapes is not like the others?

Answer 1

In order to compare the figures and find the one that is not like the others, let's compare the proportion of their width and height:

`\begin{gathered} A\colon \\ \frac{\text{width}}{\text{height}}=(5)/(4) \\ \\ B\colon \\ \frac{\text{width}}{\text{height}}=(10)/(8)=(5)/(4) \\ \\ C\colon \\ \frac{\text{width}}{\text{height}}=(10)/(6)=(5)/(3) \end{gathered}`

We can see that figure C has a different proportion, therefore figure C is the one that is not like the others.
