    Prime numbers are numbers that are divisible by the number itself and the number 1. Prime numbers go on forever, but here is a list of prime numbers up to 20: 2, 3, 5, 7,11,13,17,19 So we are looking for an answer that makes the conjecture not true. Looking at the first answer, we see that when we add two prime numbers we get a number that is not on our list of prime numbers. So this answer shows that the conjecture is not true. This answer is the correct answer. Looking at the other answers, we see that when we add two prime numbers we get a prime number. So this answer doesn't show the conjecture is not true. So this answer is no good. The third answer again shows that when we add two prime numbers we get another prime number. So this answer doesn't show the conjecture is not true. So this answer is no good. The final answer adds a prime number and a composite number. But the conjecture says we must add two prime numbers. So this answer is no good. So the first answer is correct. |dw:1444243693373:dw|

    Rewriting input as fractions if necessary: 3/16, 11/24 For (16, 24) the least common multiple (LCM) is 48. Therefore, the least common denominator (LCD) is 48. Rewriting as equivalent fractions with the LCD: 9/48, 22/48
