The length of a line segment is m. this segment is divided into: a) three equal parts; b) five equal parts. find the distance between the midpoints of the first and the last parts in each case. i need the correct answer tysm if you answer!

Consider the case where each part is of length 1. Then the midpoint of the first segment is at 1/2.

a) If there are 3 segments, the midpoint of the last segment is halfway between 2 and 3, at 2 1/2. The distance from the first midpoint to the last midpoint is ...

... 2 1/2 - 1/2 = 2 . . . . . that is, 2/3 of the total line length

When the line length is m, that is 2/3·m

b) If there are 5 segments, the midpoint of the last segment is halfway between 4 and 5, at 4 1/2. The distance from the first midpoint to the last midpoint is ...

... 4 1/2 - 1/2 = 4 . . . . . that is, 4/5 of the total line length

When the line length is m, that is 4/5·m

i would say true? if the unit was informational and it "refreshed your understanding", then true.
