Answer :
One foot is 12 inches, so 5 1/2 feet are 66 inches.
There are 36 inches in a yard, so 36 inches is 1 yard and 6 yards is 216 inches.
There are three feet in a yard, so 90 feet will be 30 yards.
There are 36 inches in a yard, so 36 inches is 1 yard and 6 yards is 216 inches.
There are three feet in a yard, so 90 feet will be 30 yards.
12 in= 1 ft
ratio and proportion
1/12= x/5.5
cross multiply
66in= 5.5 ft
36= 1 yd
36/1= x/6
x= 210 inches
3/1= 90/x
x= 30 yds
hope this helps
