6. Solve the following expressions: 6 : 3 * 2 3 * 4 : 2

Step-by-step solution:

1. Step 1: Calculate the first expression: 6 : 3 * 2.
   First, perform division: \( 6 : 3 = 2 \).
   Then, perform multiplication: \( 2 \cdot 2 = 4 \).
2. Step 2: Calculate the second expression: 3 * 4 : 2.
   First, perform multiplication: \( 3 \cdot 4 = 12 \).
   Then, perform division: \( 12 : 2 = 6 \).

Answer: 4, 6
