A piece of rope is 5.4 meters long. Art cuts off a piece that is 2.61 meters long. How much of the rope is left?
Art has 5.4 - 2.61 = <<5.4-2.61=2.79>>2.79 meters of rope left. Answer: \boxed{2.79}.
To determine how much of the rope is left, you need to subtract the length of the cut piece from the total length of the rope.
Step 1: Subtract the length of the cut piece from the total length of the rope.
5.4 - 2.61 = 2.79
Therefore, there is 2.79 meters of rope left.
