Answer:
[tex]\frac{7}{18}[/tex]
Step-by-step explanation:
In order to simplify a complex fraction you need to divide the two fractions by each other using KCF. (Keep, Change, Flip)
[tex]\frac{\frac{1}{9} }{\frac{2}{7} }[/tex]
[tex]\frac{1}{9} \div\frac{2}{7}[/tex]
Use KCF
[tex]\frac{1}{9} \times\frac{7}{2}[/tex]
[tex]1\times7=7[/tex]
[tex]9\times2=18[/tex]
[tex]=\frac{7}{18}[/tex]
Hope this helps.
