Fraction Operation Song (Tune of “Yankee Doodle”)
Let’s determine how to add a fraction and a fraction
Rewrite both the fractions with the same denominator
Add the numerators up for your numerator
Write your sum with this over that same denominator
57
Fraction Operation Song
Let us see how to subtract a fraction by a fraction
Rewrite both the fractions with the same denominator
Subtract numerators to get your numerator
Write this difference over that same denominator
58
Fraction Operation Song
Let’s determine how to multiply together fractions
Cancel numerators with either denominator
Multiply the numerators for your numerator
Multiply denominators for denominator
59
Fraction Operation Song
Let us see how to divide a fraction by a fraction
There’s a couple different methods we could use to do this
60
Fraction Operation Song
If we want to use invert-and-multiply to do this
Calculate reciprocal of fraction that’s divisor
Then you multiply divisor’s inverse by the dividend
Use the rule for multiplying fractions then to do this

If we want to use ol’ Brahmagupta’s algorithm
Rewrite both the fractions with the same denominator
Then divide the numerator of the dividend by
Numerator of divisor to obtain the quotient

Fraction Operation Song
Let us see how to divide or multiply mixed numbers
Rewrite as improper fractions, calculate with these now
64
Fraction Operation Song
Let’s determine how to add mixed number and mixed number
Rewrite as improper fractions, calculate with these or
Do addition with the fractions, carry if you need to
Then add up whole numbers, then combine for your mixed number
65
Fraction Operation Song
Let us see how to subtract mixed number by mixed number
Rewrite as improper fractions, calculate with these or
Do subtraction with the fractions, borrow if you need to
Then subtract whole numbers, then combine for your mixed number
66
Fraction Operation Song
Let’s determine how to do a fraction operation
When there is a mixed number and whole number or fraction
We adapt the rule for operating two mixed numbers
And we use this rule to complete our calculation
