If the length of the first segment is increased 3 times, and the length of the second segment is 4 times

If the length of the first segment is increased 3 times, and the length of the second segment is 4 times, then their lengths become equal. The length of the first segment is 4 cm. How many centimeters is it longer than the second?

Let’s solve this task in steps and explain each of them in detail.
1) 4 * 3 = 12 centimeters – the length of the first segment, if it is increased by 3 times;
2) 12: 4 = 3 centimeters – the length of the second segment;
3) 4 – 3 = 1 centimeters – by so many centimeters the length of the first segment is longer than the second, since the length of the first segment is 4 centimeters, and the length of the second segment is 3 centimeters.
Answer: 1 centimeter.
