Since the problem states that every number is a prime number, then the number must be a natural number greater than 1 that has no positive divisors other than 1 and itself.
2 / 1 = 2 OR 2 / 2 = 1 These numbers are prime numbers because their divisors 5 / 1 = 5 OR 5 / 5 = 1 are 1 and itself. 11/1 = 11 OR 11/11 = 1
3.9 and 5.3, when rounded off and mult. together, produce the product 20. Thus, the decimal point must follow the first two digits of your answer, whether estimate or "exact."
The coordinates of the midpoint of the line segment is the average of the coordinates of both end points. For this example above, let (x, y) be the coordinates of point Q.
