Finding the double of 4.5

To find the double of 4.5, you start by taking the given number represented by 4.5. 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 4.5 by 2. The expression (4.5 * 2) captures this operation mathematically. When you multiply 4.5 by 2, the product you get, denoted as 9, is exactly double the original number. For example, if 4.5 were 7, then 9 would be (7 * 2), which is 14. This logic applies universally to any real number represented by 4.5, making 9 the doubled value of 4.5.
