Answer;
Explanation;
Here, we want to check for the property of the given number
We look through the options definitions;
A whole number is one without any decimal attachment
The number is fully decimal so it is not a whole number
An integer is a positive whole number. The number is not a whole number so it cannot be an integer
A rational number is one that can be expressed in the form a/b
0.2782 is same as 2782/10000; so it is rational
Since the number is rational, then it cannot be irrational
That makes option c the only correct answer
