A mixed number is of the form a b/c where a, b and c are integers and a and c are non-zero.Now, a b/c = (ac + b)/c
and, by the laws governing the basic operations for integers, (ac + b) is an integer.
Therefore, the mixed number can be expressed as a ratio of two integers. It is therefore a rational number.

Is there any exemptions of mixed number being rational number?
The answer depends on what you mean by a mixed number. A mixed fraction, for example, is always a rational number - without exception.
Why are mixed numbers rational?
Because they can be expressed as a fraction
Is -4.7 a rational number?
4.7 is already a rational number. If you mean as a mixed number, this is equal to 4 7/10 or four and seven tenths.
How do you locate along the number line a rational number this is a mixed number?
A mixed number is either less than -1 or greater than +1.
Is every mixed number rational?
no but if you are not considering 1/pi or any other irrational number then the answer is yes
Are mixed numbers a rational number?

Is a mixed number a whole number?
Is a rational number an integer
Do you think a mixed number is a rational number?
Yes normally because any number that can be expressed as a fraction is rational
What type of number 17.3?
It is a rational number and also a real number.
Can the set of mixed numbers is the union of the set of integers and the set of fraction?
No, the set of mixed numbers is a subset of the set of rational numbers. For example the mixed number 1 ¼ is the same as the improper fraction 5/4 [a rational number]. Note that it is a subset, because integers are also rational numbers, but a mixed number will not be an integer. Also, any fraction between 0 and 1 will not be a mixed number.
Is -4.7 a rational number?
4.7 is already a rational number. If you mean as a mixed number, this is equal to 4 7/10 or four and seven tenths.
Are all mixed numbers rational?
Yes.A mixed number is a whole number plus a fraction.Fractions are rational, that is of the form c/dWhole numbers are rational - put them over 1 to form a[n improper] fraction a/b, eg 5 = 5/1The sum of two rational numbers is rational.
Is making a mixed number into an improper number a method to compare rational numbers?
Yes.
Is negative 9.6 a rational number?
-9.6 is a negative, real, mixed number. It's the ratio of -96 to 10, so it's rational.
Is a mixed number a rational or irrational number?
If you can write the whole thing down on paper with digits, then it's rational.
