Starting from the left end, draw a point every 3 cm, and a * * * is 60÷3- 1= 19 points (-1 is because the point at the 60th cm is subtracted and the two ends of the note are not drawn). Starting from the right, draw dots every 4 cm, and a * * * is 60÷4- 1= 14 (-1 is because the dot at the 60th cm is subtracted and the two ends of the note are not drawn). Within 60, the common multiples of 3 and 4 are 12, 24, 36, 48, so the four points drawn from left to right on the note are coincident. So there is 19+ 14-4=29 points on the note.
