Finding the double of 5.5

To find the double of 5.5, you start by taking the given number represented by 5.5. 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 5.5 by 2. The expression (5.5 * 2) captures this operation mathematically. When you multiply 5.5 by 2, the product you get, denoted as 11, is exactly double the original number. For example, if 5.5 were 7, then 11 would be (7 * 2), which is 14. This logic applies universally to any real number represented by 5.5, making 11 the doubled value of 5.5.
