To solve the expression $\frac{100}{4}(2+3)$, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses: Evaluate the expression inside the parentheses first. $2 + 3 = 5$

2. Division: Next, divide 100 by 4. $\frac{100}{4} = 25$

3. Multiplication: Finally, multiply the result by 5. $25 \times 5 = 125$

So, the final answer is 125.

Tip: Always handle operations inside parentheses first to avoid errors in calculations.
