In mathematics fraction means the numbers are in the form a/b. In fraction ‘a’ is called numerator part and ‘b’ is called denominator part and in fraction both the parts numerator and denominator are integer numbers.
Now we are going to explore fractions. Basically fractions are of three types and they are given as:
1. Proper fraction.
2. Improper fraction.
3. Mixed fraction.
Proper fraction: Fractions whose numerator is smaller than denominator is called proper fraction.
For example: - 1/3, 3/5, 6/9 etc are proper fraction.
Improper fraction: Fractions in which numerator part is larger than the denominator part is called as improper fraction.
For example: - 4/2, 8/4, 7/4 etc are improper fraction.
Mixed fraction: When the numbers consist of whole number as first part and second part as fraction are called mixed fraction.
For example: - 2(1/2), 7(3/9) etc are mixed fraction.
Now see how to add fractions and there are some rules which we have to follow while adding fraction numbers. Suppose we have two fraction numbers 2/5 and 4/5 now we want to add these two numbers before adding two fractions we have to take LCM (least common factor) of both denominators
2/5 + 4/5 = (2+4)/5
Now it is clearly seen that both the denominators are same so denominator become 5 and we add both the numerator and get:
(2+4)/5 = 6/5,
So after adding two fractions we get the result and that is 6/5.
Now take another example where both denominators are different. Two numbers are 3/2 and 5/4, now taking the LCM of denominators and the LCM is 4.
Then, 3/2 + 5/4 = (6+5)/4,
(6+5)/4 = 11/4,
So the final result is 11/4 and by this way we are going to solve the fractions.
