A plumber has a piece of pipe that is 3-meter long. He needs to cut it into sections that are 10 centimeters long. How many sections will he be able to cut?

He will be able to cut the piece of pipe into 30 sections, each 10 cm long.

Step-by-step explanation:

A plumber has a piece of pipe that is 3-meter long.

He needs to cut it into sections that are 10 centimetres long.

This means that he wants to cut the pipe into an equal number of 10-centimetre pipes.

First let us convert 3 metres to centimetres.

1 metre = 100 centimetre

=> 3 metres = 3 * 100 = 300 centimetres.

Since he wants to divide this 300 cm pipe into equal parts of 10 cm, we divide 300 cm by 10 cm. This will yield:

300 / 10 = 30 sections

Therefore, he will be able to cut the piece of pipe into 30 sections, each 10 cm long.
