Rational and irrational numbers quick check
Rational numbers are numbers that can be expressed as a fraction or a ratio of two integers. They can be written in the form a/b, where a and b are integers and b is not equal to zero.
Examples of rational numbers include:
1/2
3/4
-2/5
0
Irrational numbers, on the other hand, cannot be expressed as a fraction or a ratio of two integers. They are non-repeating and non-terminating decimals.
Examples of irrational numbers include:
√2 (square root of 2)
π (pi)
e (Euler's number)
√3 - √2
In summary, rational numbers can be expressed as fractions or ratios, while irrational numbers cannot be expressed as fractions and have non-repeating decimals.
Sure! Here's a quick check to differentiate between rational and irrational numbers:
1. Rational Numbers:
- Rational numbers can be expressed as a fraction (ratio) of two integers.
- They can be positive, negative, or zero.
- Examples of rational numbers include 1/2, 0, -5, and 3/4.
2. Irrational Numbers:
- Irrational numbers cannot be expressed as a fraction of two integers.
- They are non-repeating and non-terminating decimals.
- Examples of irrational numbers include √2, π (pi), and e (Euler's number).
Keep in mind that this is just a general overview, but it should help you understand the main differences between rational and irrational numbers. If you have any specific questions, feel free to ask!
