Decimals are real. They can be rational or irrational.
The number 1.68 belongs to the subsets of real numbers known as rational numbers and decimal numbers. As a rational number, 1.68 can be expressed as the ratio of two integers (84/50). It is also a decimal number, specifically a terminating decimal, where the digits after the decimal point eventually end.
Yes, it is. Moreover, it is also a rational number. 1.25 * 4 = 5, so 1.25 = 5/4. All rational numbers are real numbers, so 1.25 is real. Any number you can think of, using decimal notation is real. Real numbers are allowed to have an infinity of digits (behind the decimal point).
7 is a real number, as it represents a quantity on the number line. It is also a rational number, as it can be expressed as the ratio of two integers (7/1). Additionally, 7 is an integer, as it is a whole number without a fractional or decimal part. In summary, 7 is a real number, a rational number, and an integer.
Sometimes. The number '4' is real and rational. The number 'pi' is real but not rational.
We know that a real number is rational if and only if, when expressed as a decimal, it has a finite or recurring expansion. . . (put a point exactly over 8 and 2). For example, 5/4 = 1.25, 2/3 = 0.6, 20/7 = 2.857142857 or 20/7 = 2.857142
It is a negative rational number in decimal form. It is also a real number.
The number 1.68 belongs to the subsets of real numbers known as rational numbers and decimal numbers. As a rational number, 1.68 can be expressed as the ratio of two integers (84/50). It is also a decimal number, specifically a terminating decimal, where the digits after the decimal point eventually end.
It is the decimal expression of a positive rational and real number.
All real numbers have a decimal representation. Rational numbers have decimal representations that terminate or repeat infinitely. Irrational numbers have decimal representations that are non-terminating and non-repeating.
48 is rational. It can be written as a/b where a and b are integers and b is not = 0 It is written as 84/1 or 96/2. It is also a terminating/repeating decimal. (In this case, terminating decimal). Real numbers can only be rational or irrational, not both. Therefore it is only rational, not rational and irrational. b.t.w. It is also a natural number, whole number, integer, rational number, real number and complex number.
The number 4.666666 is a rational number because it can be expressed as a fraction, specifically ( \frac{14}{3} ). It is also a decimal number, with a repeating decimal part (the "6" repeats indefinitely). Additionally, it is a real number since all rational numbers are part of the real number system.
It is different kinds of numbers including a decimal number, a positive number, a rational number and a real number.
Yes, it is. Moreover, it is also a rational number. 1.25 * 4 = 5, so 1.25 = 5/4. All rational numbers are real numbers, so 1.25 is real. Any number you can think of, using decimal notation is real. Real numbers are allowed to have an infinity of digits (behind the decimal point).
7 is a real number, as it represents a quantity on the number line. It is also a rational number, as it can be expressed as the ratio of two integers (7/1). Additionally, 7 is an integer, as it is a whole number without a fractional or decimal part. In summary, 7 is a real number, a rational number, and an integer.
The number 0.2782 is a decimal number and specifically a rational number because it can be expressed as a fraction (2782/10000). It is also classified as a real number, as it can be located on the number line. Additionally, since it is not an integer, it can be considered an irrational number if it cannot be expressed as a simple fraction, but in this case, it is rational.
The number 2.454554555 is a decimal number, specifically a rational number, as it can be expressed as a fraction (e.g., 2454554555/1000000000). It is also a real number, which includes all rational and irrational numbers. The digits after the decimal point indicate that it is a non-integer.
Not necessarily. All rational numbers are real, not all real numbers are rational.
