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]
