( /10+/5)*/20-5/8

To solve the expression \(( \frac{10}{5} ) \times 20 - \frac{5}{8}\), we follow the order of operations (parentheses, exponents, multiplication and division from left to right, and addition and subtraction from left to right).

1. First, we solve the part within the parentheses: \(\frac{10}{5} = 2\)

2. Now substitute back into the expression: \(2 \times 20 - \frac{5}{8}\)

3. Next, perform the multiplication: \(2 \times 20 = 40\)

4. Now the expression is: \(40 - \frac{5}{8}\)

5. To subtract \(\frac{5}{8}\) from 40, we convert 40 to a fraction with the same denominator: \(40 = \frac{40 \times 8}{8} = \frac{320}{8}\)

6. Now subtract: \(\frac{320}{8} - \frac{5}{8} = \frac{320 - 5}{8} = \frac{315}{8}\)

Therefore, the final result is: \[ \frac{315}{8} \text{ or } 39.375 \]
