Analysis & Answers:

To make the ratio of the length and width of the small paper cut is 5 3, and there is no surplus when cutting, and the length of the paper 147 cm can only be divided by 3 and not divisible by 5, the width of the paper 105 cm can be divisible by 5, so the long side of the paper should be made the width of the small paper, and the wide side of the paper should be the length of the small paper, so that it can be obtained: 147 3 49, 105 5 21, to make the rectangular paper have no remaining, and the number of sheets should be the least, that is, the number of centimeters of length and width should be the largest, and the greatest common divisor of 49 and 21 is 7, Therefore, the number of small sheets of paper cut is: [ 147 (7 3)] 105 (7 5)] = 21 (sheets).
