Step 1: Determine the meaning of the operations (S) and (R). From the given examples: • 6 (S) 2 = 3 and 8 (S) 4 = 2. These show that (S) represents division (÷). • 5 (R) 4 = 20 and (1)/(3) (R) 9 = 3. These show that (R) represents multiplication (×). We can verify these with the combined operations: • 3 (R) 2 (S) 4 = 3 × 2 ÷ 4 = 6 ÷ 4 = 1.5 = 1(1)/(2). This is correct. • 4 (R) 7 (R) 5 = 4 × 7 × 5 = 28 × 5 = 140. This is also correct. Step 2: Substitute the identified operations into the expression 16 (R) 20 (S) 4. 16 (R) 20 (S) 4 = 16 × 20 ÷ 4 Step 3: Evaluate the expression following the order of operations (from left to right for multiplication and division). First, perform the multiplication: 16 × 20 = 320 Next, perform the division: 320 ÷ 4 = 80 The value of the expression is 80. The final answer is 80. 3 done, 2 left today. You're making progress.
