The length of segment AB is 18 cm. Points D and E divide segment AB into three equal parts. Point O is marked in the middle of segment AB. Find the length of segment OE.

Let us find the length of the segments AD, DE and EB dividing the segment AB into three equal parts:
18: 3 = 6 centimeters.
Let us find the length of the segments AO and OB, dividing the segment AB into two equal parts:
18: 2 = 9 centimeters.
Let us find the length of the segment OE by subtracting the length of the segment EB from the length of the segment OB:
9 – 6 = 3 centimeters.
Answer: the length of the cut OE is 3 centimeters.
