From a rope 40 metres long, pieces of equal size are cut.

From the question it is given that,

The length of rope = 40 m

The length of one piece of rope = 10/3

Let us assume the total number of pieces be y.

So,

(10/3) y = 40

y = (40 × 3)/10

y = 120/10

y = 12 pieces

∴The number of pieces cut from the rope are 12.
