Mixed numbers have fractional parts that must be compared; whole numbers do not.
adding fractions is like adding a WHOLE lot of parts of numbers
One way they are different is that decimals are "parts of a whole" not necessarily a whole.
A decimal number is not always smaller than a whole number. This is a decimal number 2.45 The number on the left of the decimal point shows the whole numbers. The numbers on the right of the point shows the parts/fractions. This number is not a whole number .098 This number is a whole number 2.00 This number has whole numbers and parts/fractions of the whole 2.098
An interval separates the distance between two numbers into equal parts. For example, the number 4 is an interval for the number 3 and the number 5.
decimal point
It separates the place values with positive power of ten from those with negative powers of ten. In other words, it separates the whole part of numbers from their fractional parts.
All of the counting numbers are whole numbers. Counting numbers consist of 1, 2, 3, 4, etc. Whole numbers are numbers that have no fractional parts. Since none have fractional parts, they are all whole numbers.
Mixed numbers have fractional parts that must be compared; whole numbers do not.
Integers or whole numbers
The purpose is to separate whole numbers from fractional parts of whole numbers.
Integers include 0, the negative numbers without fractional parts, and the positive numbers without fractional parts. The "without fractional parts" part of the description implies that all of the integers are whole numbers. Therefore, if you are adding integers, you are adding whole numbers.
