How to fill out rational and irrational numbers

How to fill out rational and irrational numbers

1. To fill out rational numbers, follow these steps:
2. Identify the given number as a rational number.
3. Write the number in the form of a fraction, where the numerator and denominator are integers.
4. Simplify the fraction, if possible, by dividing both numerator and denominator by their greatest common divisor.
5. If the fraction can be further simplified, continue dividing by the greatest common divisor until it is in its simplest form.
6. Write down the simplified fraction as the final rational number.
8. To fill out irrational numbers, follow these steps:
9. Identify the given number as an irrational number.
10. Write the number as a decimal, either terminating or non-terminating.
11. If the number is non-terminating, determine the pattern, if any, and write an appropriate indication (e.g., '...' or a bar above the repeating part).
12. Write down the decimal representation as the final irrational number.

What is rational and irrational numbers?

Rational numbers are numbers that can be expressed as the quotient or fraction of two integers, where the denominator is not zero. Irrational numbers are numbers that cannot be expressed as a simple fraction, meaning their decimal representation is non-repeating and non-terminating.

Who is required to file rational and irrational numbers?

The concept of filing relates more to tax documentation or reports, not directly to rational and irrational numbers themselves. Rational and irrational numbers are mathematical concepts, not typically filed.

How to fill out rational and irrational numbers?

To represent rational numbers, write them as fractions like a/b, where a and b are integers, and b is not zero. Irrational numbers are often represented using symbols or approximations, such as π or √2.
