Here in this unit we will learn about the numbers. For understanding what the different types of numbers are we will discuss various kinds of numbers used by us. The origin of numbers is natural numbers. Natural numbers start from 1, 2, 3 ... and goes up to infinite. Every natural number has a successor and every natural number except 1 has a predecessor. Before the number system was started, the counting was done by pebbles and stones. Now natural numbers are used to count. If we put zero in the beginning of natural numbers, they become whole numbers. So 0, 1, 2, 3... up to infinite makes whole numbers. Whole numbers are called measuring numbers. They help us to measure the different units like speed, distance, weight etc. So we call 0 as the starting point or the point of reference for any unit. Same as natural numbers, every whole number has a successor and a predecessor, except zero has no predecessor. Now we look at the fractions numbers, the fractions are expressed in form of a/b, where a and b are natural numbers. We say a is the numerator and b is the denominator. 2/5, 7/3 and 2/1 are the examples of the fractions. These fraction numbers can be proper fraction and improper fraction. We say any fraction is proper when the numerator is smaller than the denominator. Read More About Adding And Subtracting Rational Numbers Worksheet

On the other hand if the denominator is less than the numerator, then the fraction is called improper fraction. we see that 3/7 is the example of proper fraction as 3 < 5, and 7/3 is the example of improper fraction. A fraction is called a unit fraction, when we have 1 as the numerator. So 1/3, 1/4 etc all are the examples of unit fractions. All mathematical operators can be operated on the fractions; this means if we have two fraction numbers, we can add them, find their difference, We can multiply them and even find the quotient of the two fraction numbers. Two fractions can be compared and we can find which of the two fraction numbers are greater.
