Well. First you have to find the common denominator of 16 and 4, which would be sixteen, because both 16 and 4 decide by it. So the problem would become 13/164/16 because 1/4 equals 4/16. The answer would be 9/16.

13/161/4
you need to change 4 into 16. 4*4 is 16
so now it is 13/164/16
134=9
so it is 9/16
