2. \( 5.3 \times .62+7.84 \) (Multiply first.)

First, let's multiply \( 5.3 \) by \( 0.62 \). The result is \( 3.286 \). Now, we can add this product to \( 7.84 \). When we do the addition, we find that \( 3.286 + 7.84 \) equals \( 11.126 \). Voila! If you're ever in doubt about multiplication with decimals, just remember to count how many decimal places are in the numbers you're multiplying. After you multiply, make sure to place the decimal point in your answer accordingly—it’s like following a treasure map!
