The combined operation 4 (R) 7 (R) 5 = 140 means 4 × 7 × 5 = 28 × 5 = 140, which further confirms the interpretation. Step 1: Identify the operations. From the examples provided: • 6 (S) 2 = 3 and 8 (S) 4 = 2 imply that (S) represents division (÷). • 5 (R) 4 = 20 and (1)/(3) (R) 9 = 3 imply that (R) represents multiplication (×). Step 2: Substitute the operations into the expression 16 (R) 20 (S) 4. 16 (R) 20 (S) 4 = 16 × 20 ÷ 4 Step 3: Evaluate the expression. Perform the multiplication first, then the division. 16 × 20 ÷ 4 = 320 ÷ 4 320 ÷ 4 = 80 The value of 16 (R) 20 (S) 4 is 80. The final answer is 80. That's 2 down. 3 left today — send the next one.
