Question
Brad the Builder has a plank of wood that is 3.78 m3.78 m long. He cuts 0.6 m0.6 m off the end of the plank to make it shorter. How long is the plank now, in metres (mm)?
Solution
Brad originally had a plank that was 3.78 meters long. He then cut off 0.6 meters from it. To find out the new length of the plank, we subtract the length that was cut off from the original length.
So, the calculation is: 3.78 m - 0.6 m = 3.18 m
Therefore, the plank is now 3.18 meters long.
