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.

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
