A piece of rope is x metres long . It is cut into 4 equal parts .
a) What is the length of each part ?
b) If the length of each part is 3 metres find the length of the whole piece of rope .

a) Length of rope = x metres
Number of pieces the rope is cut into =4 
Length of each piece=x/4

b) Length of each part=3 metres 
Number of pieces of rope=4
Total length of rope =3*4=12 metres.
The total length of the rope is 12 metre .
