Step-by-step explanation:
Total length of the rope is 77 .
Let 'A' and 'B' be the two pieces into which the rope is cut.
Let 'x' be the length of rope 'A'
Therefore length of rope 'B' = 4/7(X)
Total length of rope
= A+b
=77
A+B =77
x + (4/7)×x =77
11/7×x =77
x=49 meters ( length of rope A)
Length of rope B = 4/7(49)
B=28meters.
We know that A is the largest piece
So 3/4th of rope A
= 3/4(49)
=36.75meters .
