To show that they used the same amount of ribbon you could take the 1 yard and divided into different sized equal groups. 
 1 yard divided by four equals 1/4 yard for each of four ribbons. 
 1 yard divided by six equals 1/6 yard for each of six ribbons.
 You could have ribbons the size of 1/4 our yard and 1/6 yard, but you would have different amounts of each.

Answer:
k = 3
Step-by-step explanation:
5(ky-6)=15y-30
Factor out a 5 from the right side
5(ky-6)=5(3y-6)
Divide each side by 5
ky -6 = 3y -6
Add 6 to each side
ky = 3y
divide by y
k = 3
