Finding the double of 1.5

To find the double of 1.5, you start by taking the given number represented by 1.5. Doubling means you want to find a number twice as big, so the natural operation to perform is multiplication by 2. This is why the calculation involves multiplying 1.5 by 2. The expression (1.5 * 2) captures this operation mathematically. When you multiply 1.5 by 2, the product you get, denoted as 3, is exactly double the original number. For example, if 1.5 were 7, then 3 would be (7 * 2), which is 14. This logic applies universally to any real number represented by 1.5, making 3 the doubled value of 1.5.
