LCD Riddle

You just solved the following riddle:

"We are two simplified fractions. Our LCD is 12. Our denominators are consecutive integers. The numerator and denominator of one of us has a difference of 3. The other fraction is greater than 50%. Who are we?"

Now it's your turn to make the riddle. Begin yours with "We are two simplified fractions. Our LCD is..." Then continue to give clues that will lead the reader to discover your two simplified fractions.

Be creative with your clues! Good luck!

    We are two simplified fractions. Our LCD is 20. Our denominators are consecutive integers. The numerator and denominator of one of us has a difference of 2. If you add the two numerators you get 4 if you subtract them you get 2. Who are we?

    We are two simplified fractions. Our LCD is 42. Our denominators are 11 apart. One of the fractions have a consecutive numerator and denominator. The other fraction is over 75% but it does not have a consecutive numerator and denominator. Who are we?
    (The one above is a mistake)

    We are two simplified fractions. Our LCD is 20. Our denominator is a two consecutive numbers. When you add the numerators together, it is equal to one of the denominators. One of the fraction's numerator is 50% bigger then then the denominator. when you add one fractions denominator and the numerator, it is 8.

    "We are two simplified fractions. Our LCD is 34. The sum of all the numerators and denominators of both of us is 100. Both of us are greater than 80%. The numerator of one of us is divisible by 4, while the numerator of the other one is divisible by 11. Who are we?"

    We are 3 simplified fractions. Our LCD is 12. The difference of numerator and denominator is 1 (first fraction, 2 (second fraction), and -1 (last fraction). However, the last fraction is the reciprocal of the first. What are the fractions?

    The LCD is 63. The numeral of the both fractions are added is 9. One of the numeral is 5. The addition of the numeral 5 and one of the denominator is 12. Find the two factors.

    We are two simplified fractions. Our LCD is 24. Our denominatiors have a difference of 10 between the two denominators. The numerators of the two fractions have a difference of 3. The fraction of the second fraction is less than the numerator of the first fraction. The difference between the denominator and the numerator of the first fraction is 8. Who are we?

    We are two simplified fractions. Our LCD is 14. However, the denominators are both factors of 42, and they are the same number. The two fractions are both less than 50%. If you add the two numerators then it equals an odd number. For one fraction, the difference is 6, and the other fraction is 3. Who are we?

    --REVISED VERSION--

    We are two simplified fractions. Our LCD is 12. When you multiply the numerator it is 12 and when you add it, it is 7. One of the denominator is the same as numerator of the other fraction. When you add the denominators, it comes out to be a 7. Who are we?
