I have do complete a poster for math but I have some confusing instructions at first. Please help me understand and provide an example using the directions below that were given to me:

Choose four rational numbers. At least two of your numbers should be between -1 and 1, one of which should be written as a decimal and the other should be written as a fraction. Two of the numbers should be positive and two numbers should be negative.

You need to chose what numbers to use and what math processes to involve. For the numbers between -1 and 1, you could use -.5 and 1/2. You do the rest.

To complete your math poster, you need to choose four rational numbers that meet certain criteria. Let's break down the instructions step by step:

1. Choose four rational numbers: Rational numbers are numbers that can be expressed as a fraction, where the numerator and denominator are integers (whole numbers). Examples of rational numbers include 1/2, 3/4, -2/5, etc.

2. At least two numbers between -1 and 1: This means that at least two of your rational numbers should have absolute values less than 1. In other words, they should be fractions or decimals that are smaller than 1, but greater than -1. For example, you could choose 1/2 and 0.75 as your two numbers between -1 and 1.

3. One number as a decimal and the other as a fraction: This means that out of the two numbers between -1 and 1, one should be written as a decimal and the other as a fraction. For example, you could write 1/2 as a fraction and 0.75 as a decimal.

4. Two positive numbers and two negative numbers: You need to choose two rational numbers that are positive and two that are negative. Positive rational numbers are greater than 0, while negative rational numbers are less than 0. For example, you could choose 1/2 and 0.75 as your positive numbers, and -2/5 and -0.25 as your negative numbers.

Putting it all together, here's an example set of four rational numbers that satisfy the given instructions:

Positive Numbers:
1. 1/2 (written as a fraction)
2. 0.75 (written as a decimal)

Negative Numbers:
3. -2/5 (written as a fraction)
4. -0.25 (written as a decimal)

Remember, you can choose different rational numbers as long as they meet the criteria outlined in the instructions.
