From a piece of wire, 22 dm were first cut off, and then the same amount. There are only 56 dm of wire left.

From a piece of wire, 22 dm were first cut off, and then the same amount. There are only 56 dm of wire left. how many decimeters of wire were in the piece?

Let us determine how long the wire was cut from the piece, if it is known that at first 22 decimeters were cut off, and then the same amount was cut off, that is, 22 decimeters.
22 + 22 = 44 decimetres.
Let’s determine the initial length of a piece of wire, if after 44 decimeters were cut off from it, 56 decimeters of wire remained in it.
56 + 44 = 100 decimeters.
Answer: the piece originally contained 100 decimeters of wire.
