To answer your question, I will solve the math expression step by step using LaTeX. The expression is:

$$810\div(3\times30)+250\div(20+30)$$

First, we apply the order of operations and perform the multiplication and addition inside the parentheses:

$$810\div(90)+250\div(50)$$

Next, we divide the numbers and simplify the fractions:

$$9+\frac{5}{2}$$

Finally, we add the fractions by finding a common denominator:

$$\frac{18}{2}+\frac{5}{2}=\frac{23}{2}$$

Therefore, the final answer is:

$$810\div(3\times30)+250\div(20+30)=\frac{23}{2}$$
