To start, it’s crucial to align the decimal points correctly. In this case, we have one decimal place in 13.8, which we can handle by ensuring the final result reflects this.
To make calculations easier, it’s often beneficial to eliminate the decimal temporarily. By considering 13.8 as 138 (after multiplying by 10), we can simplify the multiplication.
