To write a fraction as a mixed number, we need to figure out how many times 3 will go into 19. Divide 19 by 3 to get our whole number. 19/3 = 6. We have 6 0/3 as our mixed number so far, but we have 1/3 left over from the 19/3, since 18/3 = 6. Add 1/3 to 0/3. Your answer is 6 1/3. I hope this helps!
