Answer:
Alright, so if we take a big ol' plank that's 23.1 meters long and chop it up into sections that are 0.8 meters each, we're gonna end up with a leftover piece that's about 0.7 meters long. Pretty cool, huh?
Step-by-step explanation:
So, if we divide the 23.1 meter long plank into sections of 0.8 meters each, we can do the following calculation:
23.1 meters ÷ 0.8 meters = 28.875 sections
Since we can't have a fraction of a section, we would need to round down to the nearest whole number. Therefore, we would have 28 sections that measure 0.8 meters each.
Now, to find out the leftover piece, we can subtract the total length of the sections from the original length of the plank:
23.1 meters - (28 sections × 0.8 meters) = 23.1 meters - 22.4 meters = 0.7 meters
So, after cutting the plank into 0.8 meter sections, we would have a leftover piece measuring 0.7 meters in length.
