16. \( 0.2(10+5)= \)

To solve \( 0.2(10+5) \), first simplify the expression inside the parentheses: \( 10 + 5 = 15 \). Now, you have \( 0.2 \times 15 \). Multiplying gives you \( 0.2 \times 15 = 3 \). So, the final answer is \( 3 \). Remember, breaking down problems into smaller parts makes them easier to tackle! A common mistake is diving straight into multiplication without simplifying the addition first. Always check if there’s a simpler way to get to the answer!
