0.5 meters Let's look at the problem and create an equation expressing it. "Greg had a rope one meter long" L = 1m "Greg and his friend Brad each cut off 0.2 meter of the rope to use in Greg's tree house." L = 1m - 0.2m - 0.2m "Greg cut off another 1/10 meter of the rope to use on a chair. " L = 1m - 0.2m - 0.2m - (1/10)m Now solve for L L = 1m - 0.2m - 0.2m - (1/10)m L = 1m - 0.2m - 0.2m - 0.1m L = 0.8m - 0.2m - 0.1m L = 0.6m - 0.1m L = 0.5m So the amount of rope left unused is 0.5 meters
