Final answer:
The value of f when 6f=4 is f = 0.67.
Step-by-step explanation:
To find the value of f when 6f = 4, we need to isolate f. We can do this by dividing both sides of the equation by 6. So, f = 4/6.
Simplifying this expression, we get f = 2/3 or f = 0.67.
Therefore, the value of f is 0.67.
