  1. We are two simplified fractions. Our LCD is 24. One of us have denominator same as LCD. If we multiply each denominator, it comes out as 288. One of us, which has denominator same as LCD, has difference of 17 between numerator and denominator. The other number has difference of 7 between numerator and denominator. Who are we?

  4. We are two simplified fractions. Our LCD is 15. One of the denominators have a prime factorization of 3*5. The other denominator is one of the factors of our LCD. There should be no improper fractions, and the numerator of that fraction is a composite number. Our two numerators are 1 digit apart. Who are we?

  6. We are two simplified fractions. Our LCD is the LCM of 3 and 7 times 4. The numerators are two consecutive integers. One of the denominators times 2 minus 2 is the other denominator. The smaller denominator plus the other fraction’s numerator is the bigger denominator. The fraction with the smaller denominator has a numerator that is the GCF of 32 and 20.

  7. Our LCD is 960. We are two simplified fractions. Our Denominator of the first fraction multiplied by 5 is our LCD. Our numerators are both prime. Our numerators add up to 230. The numerator of the first fraction is 2x2x2x2x2x2+3. The product of the numerator and the denominator of the second fraction is 52,160. What are we?

  8. We are two simplified fractions. Our LCD is equal to 8x9. Their numerators are both odd and the smaller one is equal to 1. The smaller fraction's denominator is equal to 4 while the other denominator is equal to (2x2x2x2)+2. When their denominators are both equal, the numerator of the greater number is equal to 20.Who are we?

  16. We are two simplified fractions. Our LCD is 15. One of the denominators have a prime factorization of 3*5. The other denominator is one of the factors of our LCD. The denominator of the second fraction is larger than the answer to 29*8/58. There should be no improper fractions, and the numerator of both fraction is a prime number. Adding the two numerator would equal the smaller denominator. The two numerators are 1 digit apart. Who are we?
