Finding the double of 12.5

To find the double of 12.5, you start by taking the given number represented by 12.5. 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 12.5 by 2. The expression (12.5 * 2) captures this operation mathematically. When you multiply 12.5 by 2, the product you get, denoted as 25, is exactly double the original number. For example, if 12.5 were 7, then 25 would be (7 * 2), which is 14. This logic applies universally to any real number represented by 12.5, making 25 the doubled value of 12.5.
