Final answer:
To write the equation for the situation, we represent the fraction f as a variable x. The equation is x * 4 = 1/2. Simplifying the equation, we find x = 1/8.
Step-by-step explanation:
To write an equation for the situation, we need to represent the fraction f as a variable. Let's use x to represent f. The equation for the given situation is:
x * 4 = 1/2
To solve this equation, we need to isolate x. We can do this by dividing both sides of the equation by 4:
x = (1/2) / 4
When we simplify the right side of the equation, we get:
x = 1/8
So, the equation for the situation is x = 1/8.
