Using fractions in real life?
You use fractions (or some variation, such as decimals) in any situation where whole numbers are not sufficient. For example, when you want to measure the object of a length in meters, and a whole number of meters is not precise enough.
Fractions and decimals?
Fractions and decimals are different ways of notating the same thing: a number that falls between two whole numbers. In its simplest form, think about a distance or a value that is exactly halfway between 3 and 4 of something. As a mixed number, that would be 3 and 1/2 As a fraction, that would be 7/2 As a decimal, that would be 3.5 Some people refer to mixed fractions or decimal fractions to underscore the fact that they're all the same.
Why are mass numbers whole numbers?
mass numbers are whole numbers because the mass number is number of protons in an atom, plus the number of neutrons. you can only have a whole neutron and or proton, therefore, all mass numbers are whole numbers.
Are integers rational numbers?
Integers are whole numbers. Rational numbers can be fractions / decimals. But it is NEVER a whole number E.G. of rational numbers : 3/4 or 1.5
What is the difference between whole numbers and positive integers?
Whole numbers are generally speaking numbers that are "whole" or without fractions and decimals. Generally they are considered to be the natural numbers (or counting numbers) plus zero. The set of whole numbers is {0, 1, 2, 3, ...}. Positive integers are numbers in the set of integers that are greater than zero. The integers {..., -2, -1, 0, 1, 2, ...}. The positive integers {1, 2, 3, ...}. So generally the only difference is whether or not zero is included. Note that there are arguably different sets that can be called whole numbers (such as without the zero, or even somewhat rarely all integers positive and negative).

What difference does it make if the decimal is placed before or after the number?
If the number is before the decimal, it is a whole number. The numbers after the decimal represent fractions of whole numbers. For example if you had to work 8.5 hours, you would work 8 whole hours plus one half hour.
What two fractions equal 2 whole?
1 half plus 1 half equals a whole
How to find a whole number?
The whole numbers include the counting numbers, plus zero.

What are the whole numbers in 3x(2 plus 5)?
The whole numbers are 3, 2 and 5.
What are whole numbers of plus 24?
1,2,3,4,6,8,12,24
Every natural numbers is a whole numbers?
Yes, the set of whole number is all of the natural numbers, plus zero.
What is fraction 3 out of 1 plus 2 out of 1?
This is a sum involving integers (whole numbers), not fractions. 3/1 + 2/1 = 3 + 2 = 5 which can be written as 5/1.
What are the whole numbers of 21?
Whole numbers are known as zero plus the "counting numbers." (1, 2, 3, ...) So, the whole numbers of 21 would be 0 - 21. (23 numbers.)

mass numbers are whole numbers because the mass number is number of protons in an atom, plus the number of neutrons. you can only have a whole neutron and or proton, therefore, all mass numbers are whole numbers.
