Rearrange to make f the subject, showing your work step by step:

hf = hcT / b

solve for f,

divide both sides by h:

f = cT/b

not much rearranging to do there.

To rearrange the equation and make f the subject, we need to isolate the variable f on one side of the equation. Here are the step-by-step operations:

1. Begin with the equation: hf = hcT / b
2. Multiply both sides of the equation by b (to eliminate the denominator):
b * hf = hcT
3. Divide both sides of the equation by hcT (to isolate f):
(b * hf) / (hcT) = f

Therefore, the rearranged equation with f as the subject is:
f = (b * hf) / (hcT)

Remember to double-check your work and units in your calculations to ensure accuracy.
