17/36 * 26/51 = 442/1836 = 26/108.

3/16 * 4 = 12/16 = 3/4.

3 3/5 * 1 1/9 = 18/5 * 10/9 = 2/1 * 2/1 = 4/1 = 4.

13/48 * 8 7/26 = 13/48 * 215/26 = 1/48 * 215/2 = 215/96 = 2 23/96.

40/7 * 14/5 = 560/35 = 80/5 = 16.

23 * 5/46 = 23/1 * 5/46 = 1/1 * 5/2 = 5/2 = 2,5.

4 2/7 * 2 = 30/7 * 2/1 = 60/7 = 8 4/7.
