Fractions
Fraction is defined as a part of something. We use the terms denominator and numerator to
express the fraction.
Equivalent fractions
Equivalent fractions are fractions that look different but show exactly the same amount. You
can make equivalent fractions by multiplying or dividing the numerator and denominator by
the same number.
Types of fractions
1. Improper fraction
An improper fraction is a fraction where the numerator (the top number) is greater than or
equal to the denominator (the bottom number). In other words, it is top-heavy.
2. Mixed fraction
When a fraction is composed of:
1. a whole number
2. a fraction
it is called as a mixed fraction.
1. Like Fractions:
When fractions have same denominator, it is called liked fraction.
Case 1:
If the denominators are same then we can decide that the fraction which is having the
greater numerator is greater.
Case 2:
If the denominators are different then we have to convert each fraction into equivalent
fraction with the common denominator.
To make the denominator same we have to apply the concept LCM.
Comparing numerator 6 is greater than 5 hence 3/5 > ½
Multiplying fractions
1. Multiply the numerators and put in the numerator of the result
2. Multiply the denominators and put in the denominator of the result
eg:
Adding fractions
CASE 1. IF DENOMINATOR ARE SAME just add the numerator and write down the
denominator which is same for eg.
Case 2. IF DENOMINATOR ARE NOT EQUAL, make denominator equal by
To subtract two fractions, they also must have a Common Denominator
First make denominators same as done in addition then subtract numenator.eg
Recap
Fractions are defined as a part of whole.
Improper fractions have bigger numerator and small denominator
Fractions having same denominator are called like fractions.
Fractions having different denominator are called unlike fractions.
