A fraction is a number formed by the ratio of two integers. If ‘a’ and ‘b’ are two numbers, then a/b is a fraction if d≠0; otherwise, the fraction is undefined.
Some of the common examples of fractions are 5/10 , 3/2 , – 1/2 , 31/2 (mixed fraction) etc…
Positive and negative fractions are also possible. The numerator is the highest number in a fraction, while the denominator is the lowest. The fraction is incorrect if the numerator is greater than the denominator.
When a fraction is added to a whole number, we call it a “mixed number.” A proper fraction has a denominator that is greater than the numerator. Proper fractions are also known as common fractions and simple fractions.

Solved Example on Subtracting Fractions
Similar to adding fractions, when the denominators of fractions are the same, they can be easily subtracted.
Example 1 : Subtracting Fractions with Same Denominator
Subtract 3/8 – 2/8
Because the values in the denominator are the same, we can easily do subtraction of these two fractions.
3/8 – 2/8
3-2/8 = 1/8
When fractions have unlike denominators, they can’t be combined unless they’re both rewritten with the same denominator, which is known as a common denominator.
Example 2 : Subtracting Fractions with Unlike Denominator
Subtract 3/6 – 7/4
Now, in this example, the denominators of the two fractions differ. As a result, we cannot simply subtract the fractions as we did in the first example. First, we must match the denominators of the two fractions.
3/6 – 7/4
Multiply the numerator and denominator of the first fraction with 2.
We get, 3/6 = 6/12
Now multiply the numerator and denominator of the second fraction with 3.
We get, 7/4 = 21/12
Now that the denominators of both fractions are the same, we may subtract them together.
6/12 – 21/12 = 6-21/12 = -15/12
-15/12 = –5/4 ….(dividing numerator and denominator by 3)
