Answer:

[tex]\frac{27}{4}[/tex] or 6.75

Step-by-step explanation:

  1. To cancel out a fraction you multiply by the reciprocal. To make multiplying easier you can make -3 into a fraction by putting 1 under it
  2. Multiplying across, two negatives make a positive so the answer is positive

[tex](-\frac{9}{4})-\frac{4}{9}f=-\frac{3}{1} (-\frac{9}{4})[/tex]  

[tex]f=\frac{27}{4}[/tex]
