Answer

\text{80}

3 steps

The combined operation $4 (R) 7 (R) 5 = 140$ means $4 \times 7 \times 5 = 28 \times 5 = 140$ , which further confirms the interpretation.

Identify the operations.
From the examples provided:
- $6 (S) 2 = 3$ and $8 (S) 4 = 2$ imply that (S) represents division ( $\div$ ).
- $5 (R) 4 = 20$ and $\frac{1}{3} (R) 9 = 3$ imply that (R) represents multiplication ( $\times$ ).
Substitute the operations into the expression $16 (R) 20 (S) 4$.
$16 (R) 20 (S) 4 = 16 \times 20 \div 4$
Evaluate the expression.
Perform the multiplication first, then the division.
$16 \times 20 \div 4 = 320 \div 4$ $320 \div 4 = 80$
The value of $16 (R) 20 (S) 4$ is 80.
