Answer 1

Divide both the numerator and denominator by the highest number that can go into both.

-----                  -----
30    divide 2   15

ans : 13/15         . Whatever is the highest number that can evenly go into both the top and bottom is the number you divide by until you cannot divide it 

Answer 2

Divide 26 by 2 to get 13. Divide 30 by 2 to get 15. This cannot be simplified any more so your answer is 13/15. Happy to help. :)
