Instructions for a blanket call for 36 yards of yarn. A skein of yarn has 6 feet in in. How many skeins of yarn do you need?
Aloiza [94]
For this case the first thing you should know is the following unit conversion:
 1 yard = 3 feet
 Applying the conversion we have:
 6 * (1/3) = 2 yards
 Therefore the number of skeins of yarn is:
 N = (36) / (2)
 N = 18
 Answer:
 
You need 18 skeins of yarn
