Answer:
The number –55 is an integer.
Step-by-step explanation:
Consider the provided information.
Whole numbers are the numbers 0, 1, 2, 3, 4, 5,...
Natural numbers are the numbers 1, 2, 3, 4, 5,...
Integers are the whole numbers, but they include negative numbers ...-5,-4,-3,-2,-1,0,1,2,3,4,5..
Irrational numbers are numbers which are not expressible as a ratio of two integers.
Now consider the provided number –55.
From the above definition the number –55 is neither whole number nor the natural number. Also –55 is not an irrational number because it can be expressible as a ratio of two integers.
Hence, the number –55 is an integer.
