No, it isn't an integer.
56 is an integer and not a fraction. However, it can be expressed in rational form as (56*k)/k where k is an integer.
-56 is an integer so there is no fractional part.
The greatest factor of any integer is the integer itself.
56 is an integer, not a fraction and there is no sensible way to express it as a fraction.
56 + 34 = 90 is an integer, not a fraction.
56 is an integer and not a fraction. However, it can be expressed in rational form as 56/1 which cannot be simplified.
This would be impossible - since the mean of the three integers would have to be an integer, and if you divide -56 by 3, you do not get an integer.
The numbers that are divisible by 56 are in the form 56k where k is the integer constant.
No. The square root of a positive integer can only be an integer, or an irrational number.
They are (1, 56), (2, 28), (4, 14) and (7, 8).
56 is an integer and so there is not really a sensible way of writing it as a fraction or mixed number.
Any one of the infinitely large set of numbers of the form 56*k where k is an integer.
