4/5

Explanation:

Multiply 6/13 by the reciprocal of 15/26.

6/13 times 26/15
We can cross cancel 13 and 26 because both can be divided by 13. So 13 div 13 = 1 and 26 div 13 = 2.

6/1 times 2/15
Now 6 and 15 can be canceled because both are multiples of 3. So 6 div 3 = 2 and 15 div 3 = 5.

2/1 times 2/5
Multiply the numerator and the denominator horizontally.
(2 times 2 = 4)/(1 times 5 = 5) = 4/5

Answer is 4/5
