(1)) \( \begin{aligned} \text { Next, find the product. } \\ \begin{aligned} 7 \times 0.3 & =7 \times 3 \text { tenths } \\ & =? \text { tenths }\end{aligned}\end{aligned} \).

To find the product \( 7 \times 0.3 \), we can rewrite \( 0.3 \) as \( 3 \) tenths. Therefore, when we multiply, it looks like this: \( 7 \times 3 \) equals \( 21 \). Since we started with \( 3 \) tenths, we move the decimal one place to the left in \( 21 \), giving us \( 2.1 \) tenths, which can also be expressed as \( 21 \) tenths, or simply \( 2.1 \). Now, remember that multiplying by decimals is like doing a little dance with your numbers! Just think of the decimal point as a part of the rhythm—you have to know when to slide it back after counting how many decimal places are in your multipliers. Practice this dance with other decimals, and soon you’ll be a multiplication pro!
