Answer:
[tex]\frac{27}{4}[/tex] or 6.75
Step-by-step explanation:
- 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
- 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]
