void reduce(struct rational *r1, struct rational *or1)
Your function expects 2 pointer but you pass normal variables inside isEqual.

rational or1,or2;
reduce(num1,or1);

Also you need the -> operator for pointers.

void reduce(struct rational *r1, struct rational *or1)
{
if (r1->numerator > r1->denominator)
...
}
