Answer:
9/4 yds fabric per 1 ft of ribbon
Step-by-step explanation:
3/4 yd fabric is required for every 2/3 ft of ribbon. Let's put this info into an equation of ratios to figure out the number of yards of fabric required for every ONE ft of ribbon:
3/4 yd fabric 2/3 ft ribbon
----------------------- = ---------------------
x 1 ft ribbon
Use cross mult. to solve this. We obtain 3/4 = (2/3)x.
Mult. both sides by (3/2) yields (3/2)(3/4) = (3/2)(2/3)x = x.
This comes out to 9/4 yds fabric per 1 ft of ribbon.
