Subtract. write your answer in simplest form

Answer:
6 [tex]\frac{11}{15}[/tex]
Step-by-step explanation:
OK because 9 is less than 13 we have to add to nine using the whole number.
9 turns into 8 and 9 turns into 24. (15 makes a whole so we must add 15 to 9)
now we can subtract.
8[tex]\frac{24}{15}[/tex] - 2[tex]\frac{13}{15}[/tex] = 6 [tex]\frac{11}{15}[/tex]
