Question

Can someone explain this.

Answer 1

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.
