Hello... I'm Teacher Reynan

here's the solution to your problem, which is subtracting fractions

15 1/2 - 8 3/4   first change the mixed numbers into improper fraction then it becomes

31/2 - 35/4       since the denominators are not the same get the LCD (least common denominator) of 4 and 2, which is 4

                       and divide this 4 to the denominator then multiply  to the numerator, so we have

62 - 35 / 4        subtract the numerators 62 - 35, then it becomes

27/4                 now change this improper fraction to mixed numbers again,

6 3/4                this is now your final answer. :)
