Final answer:
To find the number, divide 18 by 2. The answer is 9. 18 is a product, not a sum.
Step-by-step explanation:
To find the number, we can set up an equation. Let's represent the number as x. If we multiply the number by 2, we get 2x. According to the problem, 2x = 18. To solve for x, we need to divide both sides of the equation by 2: x = 18 ÷ 2 = 9. Therefore, the number is 9.
