Hi,
Every integer is a rational number.
It is true.
We know that 1 = 1/1, 2 = 2/1, 3 = 3/1, 4 = 4/1 and so on ……. .
Also, -1 = -1/1, -2 = -2/1, -3 = -3/1, -4 = -4/1 and so on 
So it is true .
b)

whole numbers are 0,1,2,3,....
0 = 0/1 , 1 = 1/1, 2 = 2/1, 3 = 3/1, 4 = 4/1 and so on ……. . so yes it is also true
