A piece of wood is divided into two pieces in the ratio of 2:5. One piece is 10 cm long so how long is the other piece?

The length of the pother piece of the wood is 25 cm.

Step-by-step explanation:

Let the length of a piece of wood is x such that the ratio of two pieces is 2:5. Two pieces are 2x and 5 x

Length of the first piece is 10 cm. It means, 2x = 10 i. e. x = 5

We have considered that the length of other piece is 5x. It means 5*5 = 25 cm.

Hence, the length of the pother piece of the wood is 25 cm
