Answer 3

yes

Answer 4

We can change them to denominators of 108.

\(\dfrac{6}{9} \rightarrow \dfrac{6 \times 12}{9 \times 12} \rightarrow \dfrac{72}{108}\)

\(\dfrac{9}{12} \rightarrow \dfrac{9 \times 9}{12 \times 9} \rightarrow \dfrac{81}{108}\)

Since \(\dfrac{72}{108}\) is less than \(\dfrac{81}{108}\) they are not the same.
