Rhythm of the Algorithm

(a / b) x (c / d)  =  (a x c) / (b x d)
Harry Guffee


This song is available on Harry Guffee's Do the Math!


This "live" recording and sing-along helps make it easy to learn how to multiply fractions.

The product of fractions is easy to find
If you keep this algorithm in mind
(A over B) times (C over D) equals (A times C) over (B times D)
All together now- sing it one more time
Let the whole world hear
That algorithm rhyme

(A over B) times (C over D) equals
(A times C) over (B times D)
(A over B) times (C over D) equals
(A times C) over (B times D)

Try it now in Spanish, please- you're on a roll
Una mas, si, por favor en Espanol
(A sobre B) por (C sobre D) egual
(A por C) sobre (B por D)
All together now - sing it one more time
Let the whole world hear
That algorithm rhyme

(A over B) times (C over D) equals
(A times C) over (B times D)
(A over B) times (C over D) equals
(A times C) over (B times D)
