They are both rational numbers
Most rational numbers are not whole numbers. Any number which can be expressed in the form of a ratio p/q where p and q are integers with no common factor and q > 1 is a rational number which is not a whole number.
7 and 15 have the number 1 in common as they are both odd numbers. Additionally, they are both integers and prime numbers.
It follows from the closure of integers under addition and multiplication.Any rational number can be expressed as a ratio of two integers, where the second is not zero. So two rational numbers may be expressed as p/q and r/s.A common multiple of their denominators is qs. So the numbers could also have been expressed as ps/qs and qr/qs.Both these have the same denominator so their sum is (ps + qr)/qs.Now, because the set of integers is closed under multiplication, ps, qr and qs are integers and because the set of integers is closed under addition, ps + qr is an integer.Thus the sum has been expressed as a ratio of two integers, ps + qr, and qs and so it is a rational number.
A rational number is a fraction with an integer in the numerator, and a non-zero integer in the denominator. If you consider pi/2, pi/3, pi/4 (common 'fractions' of pi used in trigonometry) to be 'fractions', then these are not rational numbers.
They can be represented as a fraction of two integers.
They are both rational numbers
It is a trivial difference. If you multiply every term in the equation with rational numbers by the common multiple of all the rational numbers then you will have an equation with integers.
The fraction 12/18 can be simplified to 2/3 by dividing both the numerator and denominator by their greatest common divisor, which is 6. Since the fraction 2/3 can be expressed as a ratio of two integers and can be written in the form a/b where a and b are integers and b is not equal to 0, it is considered a rational number. Rational numbers are numbers that can be expressed as a ratio of two integers.
Most rational numbers are not whole numbers. Any number which can be expressed in the form of a ratio p/q where p and q are integers with no common factor and q > 1 is a rational number which is not a whole number.
7 and 15 have the number 1 in common as they are both odd numbers. Additionally, they are both integers and prime numbers.
No, by the very definition of rational it can be a fraction with only integers. Common sense would suggest that since irrational means not rational that is impossible.
They are both rational integers or whole numbers Their lowest common multiple is 168
They are called irrational numbers; numbers that can be expressed as a ratio of integers are called rational numbers. Some common irrational numbers are pi (3.14159...) and the square root of two.
Of the "standard sets" -10 belongs to: ℤ⁻ (the negative integers) ℤ (the integers) ℚ⁻ (the negative rational numbers) ℚ (the rational numbers) ℝ⁻ (the negative real numbers) ℝ (the real numbers) ℂ (the complex numbers) (as ℤ ⊂ ℚ ⊂ ℝ ⊂ ℂ). Other sets are possible, eg the even numbers.
If the rational number is expressed, as a fraction, in the form p/q then find the highest common factor (HCF) of p and q and divide both by the HCF.Alternatively, find any common factor and divide p and q by that factor. Then repeat with the new ratio. Continue until the HCF is 1.
Both are: -- integers -- real numbers -- rational numbers -- perfect squares -- less than 10 -- four letters long Their GCF is 1.
