20. \( 0.5 \times 0.6= \)

Did you know that multiplying decimals is just like multiplying whole numbers? You simply multiply as if there were no decimals, then count the total number of decimal places in both numbers and place the decimal point in your answer accordingly! So, for \( 0.5 \times 0.6 \), you multiply \( 5 \times 6 = 30 \) and since there’s one decimal place in each (for a total of two), you make it \( 0.30 \) or \( 0.3 \)! Speaking of real-world application, you can find decimal multiplication in everyday activities. For example, if you're cooking and need to take half (0.5) of a recipe that requires 0.6 cups of an ingredient, you just multiply! It helps in budgeting, too: if you have $0.50 and want to buy items priced at $0.60, you'd find out how much more money you need through similar calculations. Math is all around us!
