Yes, it is rational and can be written as 7/1

Any integer is a rational number, and 7 is a integer, so yes

Of course because it can be written as 7/1

7 ≠ 7/10 7 = 7/1 7/10 = 0.7 Definition: A rational number is any number α/β ( a fraction ) such that both α and β are integers. Recall, that an integer is any "counting" number between -∞ and +∞ among the set Z={..., -3, -2, -1, 0, 1, 2, 3,...} So, for instance, -1,000,004 is an integer as would +1,000,004 So to answer your question, yes, 7 is a rational number since it can be written using integers in fractional form, that is                    7 = α/β                       = 7/1         Where α = 7              and β = 1              and both α and β are found in the set              of integers,              Z = {..., -3, -2, -1, 0, 1, 2, 3,...} :-)
