The rope

Fred was learning to tie rope. He had 5 1/2 feet of rope. If each knot took up 4/5 of a foot of rope, how many knots could he make?

Correct answer:

n =  6

Step-by-step explanation:

a=521=5+21=25 2+1=210+1=211=521=5.5 ft b=54=0.8  n0=a/b=211/54=211:54=211 45=2 411 5=855=6.875  n=n0=6.875=6
