A fraction is a number representing a part of a whole. The whole may be a single object or a group of objects.
3 out of 11 parts
3 -> Called Numerator
11 -> Called Denominator
What is proper Fraction
Proper Fraction is the fraction which is less than 1 or where Numerator is less than Denominator
What is Mixed Fraction
It is combination of whole number and proper fraction
What is Improper Fraction
Improper Fraction is the fraction which is greater than 1 or where Numerator is greater than Denominator
How to convert Mixed Fractions to Improper Fractions
Obtain the mixed fraction. Let the mixed fraction be 52/6
Identify the whole number and the numerator (top) and denominator (bottom) of the proper fraction.
Apply the formula
How to convert Improper Fractions to Mixed Fraction
Obtain the improper fraction.
Divide the numerator by the denominator and obtain the quotient and remainder.
Write the mixed fraction as
Quotient (Reminder/ denominator)
Here Numerator is greater than denominator, So Improper fraction
Now dividing 11 by 3, we get reminder as 2
So 11/3 =
How to Represent Fraction on Number Line?
We can show fractions on a number line. In order to represent 1/2 on the number line, draw the number line and look for the portion between 0 and 1
Now, divide the gap between 0 and 1 into two equal parts. The point of division represents 1/2.
To represent 1/4 on a number line, we divide the gap between 0 and 1 into 4 equal parts
First point will represent ½
Second point will represent 2/4 =1/2
Third point will represent 3/4
More points about Fraction
1) If the numerator and the denominator of a fraction have no common factor except, then it is said to be in its simplest form or lowest form.
2) Equivalent fractions are fractions that have the same value in its simplest form.
2/6, 1/3, 6/18 are equivalent fractions as they have same value
3) The equivalent fraction of a given fraction is obtained by multiplying both the numerator and the denominator of the given fraction by the same number.
Equivalent Fraction can be obtained by multiplying both the numerator and the denominator of the given fraction by the same number.
2/3 = 2×3/3×3= 6/9
2/3 = 2×5/3×5= 10/15
2/3 = 2×7/3×7= 14/21
Comparison, Addition and subtraction of Fraction
Fractions with the same denominators are called like fractions.
1/3, 2/3 are Like Fractions
¼ ,3/4 are like Fractions
Fractions with different denominators are called unlike fractions.
1/3 , 2/5 are Unlike Fractions
Comparison, addition and subtraction of Like Fraction
Comparison: The numerator value decides the larger value.
Addition: The numerator adds to provide the final fraction value.
Subtraction: The Numerator subtract to provide the final fraction value.
Comparison, addition and subtraction of Unlike Fraction
First we need to convert the unlike fraction to like fraction using the LCM of the denominators
And then it works like “like” Fraction
1) Compare 2/3 and 5/7
LCM of denominator is 3 and 7 is 21
So converting them equivalent Like fractions
2/3 = 2×7/3×7 = 14/21
5/7 = 5×3/7×3 = 15/21
Now 15/21 > 14/21
So 5/7 > 2/3
2)Perform the below Addition
LCM of 2 and 3 is 6
So converting them into equivalent Like Fractions
½ = 3/6
1/3 = 2/6
Comparison, Addition and Subtraction of Mixed Fraction
Two mixed fraction can be added or subtracted by adding or subtracting the whole number of the two fractions and then adding or subtracting the fractional parts together.
Two mixed fractions can also be converted into improper fractions and then added or subtracted.
