1) 13/2 * 7/13 = (13 * 7) / (2 * 13) = 91 / 26 = 3.5

2) 20/3 * 9/25 = (20 * 9) / (3 * 25) = 180 / 75 = 2.4

3) 58/11 * 11/29 = (58 * 11) / (11 * 29) = 638 / 319 = 2

4) 16/3 * 9/32 = (16 * 9) / (3 * 32) = 144 / 96 = 1.5

5) 75/14 * 7/15 = (75 * 7) / (14 * 15) = 525 / 210 = 2.5

6) 32/5 * 9/16 = (32 * 9) / (5 * 16) = 288 / 80 = 3.6
