Segment BC = 3 cm, which is equal to the segment length equal to 5/6 BC.

Segment BC = 3 cm, which is equal to the segment length equal to 5/6 BC. which is equal to the segment 5/6 of the length which is equal to the length of the segment BC

1. Let’s find the length of the segment if it is known that its length is 5/6 of the BC segment, and the length of the BC segment itself is 3 cm:

x = 5/6 * 3 = 15/6 = 2 3/6 = 2 1/2 cm;

Answer: the length of the segment is 2 1/2 cm.

2. Find the length of the segment if it is known that 5/6 of its length are equal to the length of the segment BC, and the length of the segment BC itself is 3 cm. Let the segment be equal to x:

5/6 * x = 3;

x = 3 * 6/5 = 18/5 = 3 3/5 cm;

Answer: the length of the segment is 3 3/5 cm.
