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

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

2. Division: Perform the division next. $\frac{100}{4} = 25$

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

So, the solution is $\boxed{125}$.
