This big band arrangement explains the procedures for the addition and subtraction, multiplication and division of mixed numbers.

A mixed number
Is a number that is equal to the sum 
Of a whole number and a fraction
That's why it's called a mixed number

To add or subtract mixed numbers 
Add the whole numbers; add the fractions
Subtract the fractions; subtract the whole numbers
Rename as required

To multiply or divide mixed numbers
Rename them as improper fractions
The product of fractions is equal to 
The product of the numerators 
Divided by the product of denominators

To divide mixed numbers
Multiply the dividend
Times the reciprocal of the divisor
To determine the quotient
Oh yeah
