Answer 1

Problem Analysis

We are given three numbers with the following information: - The sum of the three numbers is 10.7. - The first number is 4 times larger than the second number. - The third number is 2.3 larger than the second number.

We need to find these three numbers.

Solution

Let's assume the second number is x.

According to the given information: - The first number is 4 times larger than the second number, so the first number is 4x. - The third number is 2.3 larger than the second number, so the third number is x + 2.3.

The sum of the three numbers is 10.7, so we can write the equation:

4x + x + (x + 2.3) = 10.7

Simplifying the equation:

6x + 2.3 = 10.7

Subtracting 2.3 from both sides:

6x = 8.4

Dividing both sides by 6:

x = 1.4

Now we can find the other two numbers: - The first number is 4 times larger than the second number, so the first number is 4 * 1.4 = 5.6. - The third number is 2.3 larger than the second number, so the third number is 1.4 + 2.3 = 3.7.

Therefore, the three numbers are: - First number: 5.6 - Second number: 1.4 - Third number: 3.7

Answer

The three numbers are 5.6, 1.4, and 3.7.
