Jackson has a 2-meter plank of wood. He cuts two pieces of wood that are each 0.55 meter long. Then he cuts another piece that is 0.28 meter long. He uses the remainder of the wood to make a ramp. What length of wood did he use for the ramp?

2 - (0.55 + 0.28) = x

1.17 To find the length of wood Jackson used for the ramp, we need to calculate the total length of wood that he used for the two pieces and subtract it from the length of the original plank.

First, add the lengths of the two pieces of wood:
0.55 meter + 0.55 meter = 1.1 meters

Now, add the length of the third piece:
1.1 meters + 0.28 meter = 1.38 meters

To find the length of wood that Jackson used for the ramp, subtract the total length of the pieces from the length of the original plank:
2 meters - 1.38 meters = 0.62 meters

Therefore, Jackson used 0.62 meters of wood for the ramp.
