Answer:

9 packs

Step-by-step explanation:

\frac{89}{10} = 8\frac{9}{10}

Since you can't buy \frac{9}{10} of a pack, you must round up to 9.

Answer: 9 packs

Step-by-step explanation:

  • Mrs. Marks wants 89 pens.
  • Pens come in packs of 10

89 is about 90. The pens come in packs of 10, so divide 90 by 10 and the quotient is 9.
