Hey!
To divide fractions, you have to keep, change, flip.
Keep 3 1/2(7/2)
Change ÷ to ×
Flip 2 1/4(9/4) = 4/9
Now multiply the improper fractions
[tex] \frac{7}{2} \times \frac{4}{9} = \frac{28}{18} = 1 \frac{10}{18} = 1 \frac{5}{9} [/tex]
The 1st choice matches the answer. The answer is the 1st choice.
Good luck and hope this helps! :)
