Answer 2

Step-by-step explanation:

$\frac{3f}{4} - \frac{f}{5} = \frac{5(f - 4)}{8} \\ \frac{3f \times 5}{4 \times 5} - \frac{f \times 4}{5 \times 4} = \frac{5f - 20}{8} \\ \frac{15f - 4f}{20} = \frac{5f - 20}{8} \\ \frac{11f}{20} = \frac{5f - 20}{8} \\ 11f \times 8 = 20(5f - 20) \\ 88f = 100f - 400 \\ 400 = 100f - 88f \\ 400 = 12f \\ f = \frac{400}{12} \\ f = \frac{100}{3}$
