12(5-3)/23(5•5)

Let's simplify the expression step by step. 1. Start with the expression: \( 12(5 - 3) / 23(5 \cdot 5) \) 2. First, simplify the expression inside the parentheses: \( 5 - 3 = 2 \) So, we have: \( 12(2) / 23(5 \cdot 5) \) 3. Then, evaluate \( 5 \cdot 5 \): \( 5 \cdot 5 = 25 \) Now, the expression becomes: \( 12(2) / 23(25) \) 4. Now, multiply: \( 12 \cdot 2 = 24 \) Thus, we have: \( 24 / (23 \cdot 25) \) 5. Now evaluate \( 23 \cdot 25 \): \( 23 \cdot 25 = 575 \) 6. Therefore, the expression simplifies to: \( 24 / 575 \) 7. Finally, to express this as a fraction, we say: \( \frac{24}{575} \) So, the simplified expression is \( \frac{24}{575} \).
