If it takes 9 yards of material to make 6 pairs of window drapes, how many yards are required to make 8 pairs of drapes?

12

Step-by-step explanation:

6/9 tells you that you need 2/3 of matirial per drape

so 12 x 2/3 gets you 8

12 yards of matirial for 8 drapes

When solving this equation you would need 12 drapes for 8 pairs

Steps for solving this equation:

Step One: 9÷6=1.5

1.5 for each pair of drapes, so if we have eight drapes we need to multiply 1.5 by 8.

Step Two: 1.5*8=12

ANSWER: 12 drapes
