Solution to the Sum of Two Numbers Problem

To find the two numbers whose sum is equal to 1, given that one-third of the first number is equal to 0.4 times the second number, we can set up a system of equations and solve for the two numbers.

Let's denote the first number as x and the second number as y.

We are given the following information: 1. The sum of the two numbers is 1: x + y = 1 2. One-third of the first number is equal to 0.4 times the second number: (1/3)x = 0.4y

Solving the System of Equations

We can solve this system of equations to find the values of x and y.

First, let's express x in terms of y using the second equation: (1/3)x = 0.4y This can be rewritten as: x = 1.2y

Now, we can substitute the expression for x into the first equation: 1.2y + y = 1 Solving for y: 2.2y = 1 y = 1 / 2.2 y = 5 / 11

Substituting the value of y back into the expression for x: x = 1.2 * (5 / 11) x = 6 / 11

Conclusion

The two numbers that satisfy the given conditions are: x = 6 / 11 and y = 5 / 11.

This means that the sum of these two numbers is indeed 1, and one-third of the first number is equal to 0.4 times the second number.
