The arithmetic mean of two numbers 4.4. Find these numbers if one of them is 1.4 larger than the other.

To solve this problem, remember, in order to find the arithmetic mean, you need to add all the numbers and divide their sum by their number. Let the first number be x and the second number (x + 1.4). Knowing that the arithmetic mean is 4.4, we will compose the equation.
x + x + 1.4 = 4.4;
2x + 1.4 = 4.4;
2x = 4.4-1.4;
2x = 3;
x = 3/2 = 1.5 cm.
The second number is 1.5 + 1.4 = 2.9 cm.
Answer: 1.5 cm, 2.9 cm.
