Ruby uses 1/4 yard of ribbon to make 2 bows. which expression shows the length of ribbon in each bow?

What you can do in this case is a rule of three to determine the length of each bow.
 We have then:
 1/4 ---> 2
 x > 1
 Clearing x we have:
 x = (1/2) * (1/4)
 x = 1/8
 
 the length of ribbon in each bow is
 x = 1/8
 Equivalently:
 x = (1/4) / 2
 Option 3

Where the answer choices?
