Step-by-step explanation:

Answer:

[tex] \sf{\frac{1}{3}}[/tex]

[tex]{ \longmapsto \sf{ \frac{3}{7} \times \frac{7}{9} }}[/tex]

Multiply the numerators and the denominators.

So,

[tex]{ \longmapsto \sf{ \frac{3}{7} \times \frac{7}{9} = \sf \red{ \frac{21}{63} } }}[/tex]

Then,

Cancel 21 And 63

So,After Cancelling It We Get,

[tex] { \longmapsto{ \sf{ = \frac{1}{3} }}}[/tex]
