13 / 6 is equal to 2.17 or 2 17/100
6 over 13, as a percentage = 100*6/13 = 600/13 = 46.154 %
6/7 * 6/13 = (6*6)/(7*13) = 36/91
4 over 13
It is: 5/6 minus 6/13 = 29/78
48/104 = 24/52 = 12/26 = 6/13
(5/6) / (13/12) = (5/6) x (12/13) = (5/1) x (2/13) = 10/13
It is: 6 and 13/20 = 6.65
13/6
6/13 × 1/52 = 3/338
89/13 is improper. Therefore, you can reduce it to 6 11/13 (6 and 11 over 13). It cannot be simplified past that.
5/13 + 6/11 = = 133/143
6/13 divided by 6/12 = 6/13 * 12/6 = 72/78 (reducible to 12/13) This is immediately confirmed because dividing by 6/12 or 1/2 is effectively multiplication by 2.
