Answer:

$\frac{27}{4}$ 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

$(-\frac{9}{4})-\frac{4}{9}f=-\frac{3}{1} (-\frac{9}{4})$

$f=\frac{27}{4}$
