Hi, I need help because I'm really stuck on this math word. Can someone please define what rational coordinates means what? I really need help fast because this project is due today!
Thank You :)
In number theory, a rational point is a point in space each of whose coordinates are rational; that is, the coordinates of the point are elements of the field of rational numbers, as well as being elements of larger fields that contain the rational numbers, such as the real numbers and the complex numbers.
A rational number is a number which can be expressed exactly as a fraction or a ratio.
so your coordinates would NOT contain any square roots.
Thank You Reiny and Myia.
i need to know the answer for this question!!!.
i need to know if counting numbers are rational numbers?
pleaseeee someone tell me i need helppp.
Of course! I can definitely help you with that. "Rational coordinates" refer to coordinates that are expressed as rational numbers. A rational number is any number that can be expressed as a fraction, where the numerator and denominator are both integers and the denominator is not zero.
To find rational coordinates, you need to determine whether the given coordinates can be expressed as fractions. If the coordinates are already given as fractions, then they are rational coordinates. If the coordinates are decimals or whole numbers, you'll need to determine whether they can be written as fractions.
For example, let's say you have the coordinates (2.5, -3.75). To check if these are rational coordinates, you can check if they can be written as fractions. In this case, 2.5 can be written as 5/2, and -3.75 can be written as -15/4. So, the rational coordinates for (2.5, -3.75) would be (5/2, -15/4).
Remember to always simplify the fractions if possible. In our example, 5/2 and -15/4 can both be simplified. 5/2 simplifies to 2.5, while -15/4 simplifies to -3.75.
I hope this explanation helps you with your project! Let me know if you have any further questions.
