-5/4 / 2 3/5 convert mixed number

-5/4 / 13/5 reciprocal of 13/5

-5/4 / 5/13 multiply straight-across 

-25/52 cannot be reduced

first make everything improper, so it would be

-5/4 divided by 13/5

now you need a common denominator and the least common multiple is 20, so multiply the first one by 5 to get a denominator of 20 and the second one by 4 to get a denominator of 20.

now we have -25/20 divided by 52/20.

this is the same as -25 divided by 52 because you can multiply both the numerator and denominator by 20 and it wont change the answer.
this means the answer is -25/52.
