Finding the double of 31.5

To find the double of 31.5, you start by taking the given number represented by 31.5. 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 31.5 by 2. The expression (31.5 * 2) captures this operation mathematically. When you multiply 31.5 by 2, the product you get, denoted as 63, is exactly double the original number. For example, if 31.5 were 7, then 63 would be (7 * 2), which is 14. This logic applies universally to any real number represented by 31.5, making 63 the doubled value of 31.5.
