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.

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

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
