What numbers can be integers rational and real number?
Every counting number, and the negative of it, are real, rational integers.
Are all real numbers integers?
No, all integers are real numbers, but not all real numbers are integers. For example, 1.25 is a real number and a non-integer.No.
What is an integer that is not a real number?
There is no integer which is not a real number.
Is every integer a real number?
Yes, all integers are considered to be real numbers.
What is an integer that is a real number?
All integers are real numbers.
Is every rational number a real number true or false?
Yes. Rational numbers are always the quotient of two integers. Integers are always real, and you cannot divide a real number by another real number and get an imaginary number. So, true.
What number does the number -1 belongs?
Integers, odd integers, negative integers, odd negative integers, rational numbers, negative rational numbers, real numbers, negative real numbers, square roots of 1, etc.
How is zero a real number?
Zero is a an integer and, since all integers are real numbers, zero is a real number.
Is a rational number a subset of the set of integers?
not necessarily... An integer is a rational number, but so is any real number between consecutive integers.
Every real number is an integer?
Integers are a subset of real numbers. All integers are real numbers, but not the other way around. Real numbers, without going into great detail, are numbers that can be drawn on a standard x-y graph. This includes integers, fractions & decimals, common constants such as pi and e, etc. Taking the square root of negative number would result in an imaginary number (which are not a real numbers.) Integers are essentially whole numbers (numbers that can be written without a decimal or in fraction form).
A real number that cannot be expressed as a ratio of two integers?
An irrational number.
When is a number irrational?
When it is a real number that cannot be expressed as a ratio of two integers.
