Fractions consist of two numbers. The top number is called the numerator. The bottom number is called the denominator.
To add two fractions with the same denominator, add the numerators and place that sum over the common denominator.
How to Add Fractions with different denominators:
Find the Least Common Denominator (LCD) of the fractions
Rename the fractions to have the LCD
Add the numerators of the fractions
Simplify the Fraction
Mixed numbers consist of an integer followed by a fraction.
How to add two mixed numbers whose fractions have the same denominator:
Add the numerators of the two fractions
Place that sum over the common denominator.
If this fraction is improper (numerator larger than or equal to the denominator) then convert it to a mixed number
Add the integer portions of the two mixed numbers
If adding the fractional parts created a mixed number then add its integer portion to the sum.
