Rational number.
<h2>
Step-by-step explanation:</h2>
Real number---
A real number is a number which is a value which is used to represent a distance on a real line.
It is divided into two categories--
<em>1) </em>
<em>Rational Number--</em>
A rational number is a number which is written in the form of p/q where p and q are integers and q is not equal to zero.
Also, the decimal representation of such a number is recurring or a terminating decimal.
<em>2)</em>
<em>Irrational number--</em>
A rational number is a number which could not be written in the form of p/q where p and q are integers and q is not equal to zero.
Also, the decimal representation of such a number is non-terminating and non-recurring decimal.
We are given a number as:
0.2782
The decimal number is terminating decimal.
Hence, the number is a rational number.
( It is not a whole number because the whole number do not exist in decimal.
They are numbers such as: {0,1,2,3,....}
and integers are the collection of positive and negative whole numbers)
