Question

Shaun is painting a fence. After finishing three-eighths of the length of the fence he finds that
he has painted 15 feet. Let f be the total length of the fence, set up an equation like one of
those in 4(b) and solve to find f. Use either of the two methods.

Answers

  1. Answer: F = 40
    Step-by-step explanation:
    *Important: I do not know what the methods mentioned in 4b are, nor do I know its equation. Please take this into account.
    What we know:
    • 3/8 is equal to 15 ft
    • F is the total amount of fence painted
    • We need to set up and solve the equation
    How we do this:
    Using basic division, this equation is solveable.
    Process:
    • Divide to find 1/8                                                  15/3 = 5 (1/8f = 5)
    • Multiply to find total                                            5 x 8 = 40  
                                                                                           (1/8 x 8 = 8/8)
    Solution:
    F = 40
    8(5) = F

  2. Answer: x = 40
    Step-by-step explanation:
    let f be the total length of the fence:
    (3/8)f = 15
    divide both sides by 3/8
    f = 15 x 8/3
    f = 120/3
    f = 40
