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 x 8 = N

  N ÷ 48 = 8

• 8 x 48 = N

  48 ÷ N = 8

• 8 x N = 48

  48 ÷ 8 = N

• N x 48 = 8

  8 ÷ 48 = N

Draw an array on a piece of paper for 7 x 6. Break the array apart to find the product.

What equations below will solve for

7 x 6?

• (5 x 6) + (2 x 6) = N

• (5 x 7) + (2 x 7) = N

• (1 x 6) + (5 x 7) = N

• 6 x (7 + 6) = N
