7/13 is already in its most sim plified form. Reason ; both '7' and '13' are prime numbers , and therefore do not have any common factors.
No; it is 1/7 simplified.
It is: 7/13 when simplified
7/13
28/52 = 7/13
7/8 − 2/6 = 13/24 simplified.
It is: 28/52 = 7/13 simplified
13/4
It can not be simplified further.
13/9 cannot be simplified.
7/8 - 10/13 = 91/104 - 80/104 = 11/104 which cannot be simplified.
3/7 is simplified.
9 over 13 NO! 9/7 * 9/6 = 9/7 * 3/2 = 27/14 which can be simplified to 113/14 At the second stage 9/6 was simplified to 3/2 using the common factor 3.
