given data:
[tex]\begin{gathered} \frac{7}{21}\text{ and }\frac{21}{24} \\ \end{gathered}[/tex]
to find whether they form an proposition.
using cross product,
[tex]\begin{gathered} \frac{7}{21}\cdot\frac{21}{24} \\ 24\cdot7=21\cdot21 \\ 168\ne441 \end{gathered}[/tex]
the cross product are not equal.
Thus, they donot form a proposition.
