A real number that is not rational?
Real numbers are any numbers that could be on a number line. Rational numbers are numbers that can be expressed as fractions. Real irrational numbers are things like pi or the square root of 2.
Can irrational numbers be placed on a number line?
Yes. In fact, a number line would be full of an uncountably many infinite number of discontinuities (holes) without them and hence would not be a line, so in fact irrational numbers MUST be placed on the number line in order for it to exist.
What is the boundary point of rational numbers?
The boundary of the set of rational numbers as a subset of the real line is the real line.
What is Difference between rational numbers and integers?
Integers are WHOLE numbers, like 3, 18, 34, and 256. Rational numbers are any numbers which can be expressed as a ratio of two integers - 3/4 is a rational number. 124.45 is a rational number. In other words, rational numbers INCLUDE all integers. Fractions are Rational numbers.The natural number line starts at 1, and goes up by 1 each time. 1, 2, 3, 4, 5...The whole number line includes the natural, but starts at 0. 0, 1, 2, 3, 4, 5...The integer number line includes the whole number line, but adds its negative counterparts. ...-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5...The rational number line includes the integernumber line, but includes fractions (where the numerator is an integer and denominator is a non-zero integer.) ...-1, -1/2, 0, 1/2, 1...
Does every point on the real number line correspond to a rational number?
No. There are several real numbers that are not rational (e.g. pi). However, every rational number is also a real number. In general, whole numbers/natural numbers is a subset of the integers (i.e. every whole number is an integer), the integers is a subset of the rationals, the rationals are a subset of the real numbers. I think the real numbers are a subset of the complex numbers, but I'm not 100% positive on that.
Is the number line a graph of rational numbers?
The number line includes all rational numbers but also has irrational ones. It is the REAL number line. The square root of non-perfect squares are on it and pi is also on it and they are not rational.
Where are the positive rational number placed on a horizontal number line?
above 0
Can rational numbers be ordered on a number line?
Yes.
Is a real number always irrational?
Real numbers can be rational or irrational because they both form the number line.
How can a number line be used to compare rational numbers?
because the # line shows the rational #'s in order from least to greatest
Does real number line correspond to an irrational number?
No. The real number line corresponds to rational AND irrational numbers.
What is the density property in Math?
The Density Property states that, between two rational numbers on a number line there is another rational number. Mark some fractions on a number line. No matter how dense the number line is, there still is another number between the two numbers.
all numbers that can be written on the number line that include rational and irrational numbers?
That would be the real numbers.
A real number that is not rational?
Real numbers are any numbers that could be on a number line. Rational numbers are numbers that can be expressed as fractions. Real irrational numbers are things like pi or the square root of 2.
Is 1.68 a real number and why?
Yes, because it can be located on a number line.
What is 5.1 and 1.5 on the number line?
They are two points representing rational numbers.
Can rational number be on a number line?
Yes,a rational number can be on a number line :D
