Let's break down the first expression: \( 6+\frac{1}{2} \) of \( 30 \div(9-6) \). First, calculate \( 9-6 \) which equals \( 3 \). Now, proceed with \( 30 \div 3 = 10 \), then \( \frac{1}{2} \) of \( 10 \) is \( 5 \). Finally, add \( 6 + 5 \), yielding \( 11 \). Now for the second expression \( 3^{2}+5 \times 3-6 \div 3 \): Start with \( 3^2 = 9 \). Next, compute \( 5 \times 3 = 15 \) and \( 6 \div 3 = 2 \). Putting it all together gives \( 9 + 15 - 2 = 22 \). So, the answers are \( 11 \) and \( 22 \)!
