HELPPP FASTT I WILL MARK BRAINLIST

~Hello There!~
Turn both mixed numbers into improper fractions
[tex]\frac{7}{2} / \frac{9}{4}[/tex]
Keep the first fraction in its position, flip the second one upside down and turn the divide symbol into a multiply symbol.
[tex]\frac{7}{2} * \frac{4}{9}[/tex]
Now just multiply them to get:
[tex]\frac{28}{18}[/tex]
Turn this into a mixed number:
[tex]1 \frac{10}{18}[/tex]
Simplify this into:
[tex]1 \frac{5}{9}[/tex]
Therefore a = 1, b = 5 and c = 9
Hope This Helps You!
Good Luck :)
Have A Great Day ^_^
