Writing a Fraction

• A fraction has two parts. 

• The number on the top of the line is called the numerator. It tells how many equal parts of the whole or collection are taken.  

• The number below the line is called the denominator.  It shows the total divisible number of equal parts the whole into or the total number of equal parts which are there in a collection. 

Proper Fraction: where the numerator is smaller than the denominator

Improper Fraction: where the numerator is larger than the denominator

Mixed Number: a whole number with a proper fraction

Adding/subtracting Fractions

• Fractions that have unlike denominators (are not the same bottom number) need to be changed into a common denominator

• After you create a common denominator (they both have the same bottom number) then you can add/subtract the top numbers
