The length of one side of the triangle is 6 cm. The second side is 2/3 of the length of the first

The length of one side of the triangle is 6 cm. The second side is 2/3 of the length of the first, and the third is 0.75 of the first.

We will solve this task in steps and explain each of them in detail.
1) 6 * 2/3 = (6 * 2) / 3 = (2 * 2) / 1 = 4/1 = 4 centimeters – the length of the second side, since its length is 2/3 of the length of the first, and the length of the first side equal to 6 centimeters;
2) 6 * 0.75 = 4.5 centimeters – the length of the third side, since its length is 0.75 of the length of the first, and the length of the first side is 6 centimeters.
Answer: 4 centimeters; 4.5 centimeters.
