Why does a rational number plus a rational number or a rational number multiplied by a rational number equal to rational number?
The way in which the binary functions, addition and multiplication, are defined on the set of rational numbers ensures that the set is closed under these two operations.
What are the differences of rational numbers and irrational numbers?
Rational and irrational numbers are both real numbers. Rational numbers are those that can be expressed as a ratio of two integers, a/b where b is not 0. An irrational number cannot. Equivalently, a rational number can be expressed as a terminating or recurring decimal, an irrational number cannot. Or more generally, a rational number can be expressed as a terminating or recurring sequence of digits in any integer base (eg binary or hexadecimal), an irrational number cannot. Although there are an infinite number of rationals and irrationals, the order of infinity of irrationals is greater.
What rational numbers are real numbers?
All rational numbers are real numbers.
Are rational numbers is an irrational numbers?
yes * * * * * No. Rational and irrational numbers are two DISJOINT subsets of the real numbers. That is, no rational number is irrational and no irrational is rational.
Is 0.10100100010000 a rational number?
Since it has a terminating decimal (or binary or to any other rational base) representation, it must be rational.
What are rational and rational numbers?
Rational numbers are numbers which can be written in the form p/q where p and q are integers and q > 0. Rationals is often used as an abbreviation to refer to the set of all rational numbers.
Why does a rational number plus a rational number or a rational number multiplied by a rational number equal to rational number?
The way in which the binary functions, addition and multiplication, are defined on the set of rational numbers ensures that the set is closed under these two operations.
Is it possible for a rational number to be a whole number but not an integer?
Whole numbers and integers refer to the same set of numbers.
How many rational numbers are there between two consecutive rational numbers?
There are no consecutive rational numbers. Between any two rational numbers there are an infinity of rational numbers.
Can rational be defined as a number?
No. Rational can be an adjectival form of ratio but it can also refer to a process or behaviour that has been thought through. In the latter case it has nothing to do with numbers.
Is 3.9 rational or irrational?
If there are no numbers after the 9 it is rational
What is the sum of the binary numbers?
The sum of binary numbers is also a binary number.
Why is it possible to have decimal numbers?
It is possible to have numbers in ANY base. Binary, octal and hexadecimal are used extensively in computers. Furthermore, the base can be any positive number - it does not even need to be rational.
Are some rational numbers are not real numbers?
No. Rational numbers are numbers that can be written as a fraction. All rational numbers are real.
Are rational numbers whole numbers?
The set of rational numbers includes all whole numbers, so SOME rational numbers will also be whole number. But not all rational numbers are whole numbers. So, as a rule, no, rational numbers are not whole numbers.
Is the difference of rational numbers a rational number?
Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction. All natural numbers are rational.
Is 6.6 irrational or rational?
6.6 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
