There are 48 liters of water needed to finish filling the dunk tank at the carnival. Each container holds 8 liters of water. How many containers are needed to finish filling the dunk tank? Represent the problem using multiplication and division sentences and a letter for the unknown. Solve.

• $48\times c=8$ and $48\div8=c$

• $48\div8=c$ and $8\times c=48$

• $8\div c=48$ and $8\times c=48$

• $c\div8=48$ and $48\div c=8$

There are 4 rows of 7 chairs setup for the Magic Show. A worker sees the large number of people lined up and doubles the number of rows of chairs. They are shown below. Explain how the array represents both 8 × 7 and 2 × (4 × 7).

• The array shows 8 rows of 7. 8 rows of 7 can be written as 8x7.

  4x7 is the same thing as 8x7

• This can be written as 2x (4x7) because it's 4x7 two times. The whole array is 8 rows of 7. 8 rows of 7 can be written as 8x7.

• 2x4x7 is the same as 8x7.
