Question 2.
Use multiplication and division to find the secret path through each maze. The starting and ending points are marked for you. You can only move one space up, down, over, or diagonally each time. Write four equations to explain the path through the maze.
ex 3 × 4 = 12
12 ÷ 2 = 6
6 × 6 = 36
36 ÷ 9 = 4

a.  81 ÷ 9 = 9
9 × 4 = 36
36 ÷ 6 = 6
6 × 7 = 42

2 × 9 = 18
18 ÷ 3 = 6
6 ÷ 3 = 2

Question 4.
Ryan bought 4 dozen eggs. His recipe for cookies calls for 3 eggs in each batch. How- many batches of cookies can he make with the eggs he bought?
