1 4/15 Because 19 can fit into 15 only one time and the remainder is 4/15 so 1 would be your whole number and 4/15 would be your little other fraction :)
Okay so you divide 19 into 15: 15 goes into 19 1 time and 19-15=4 so you take the top number for you mixed number the 4 is the numerator and 15 is denominator
