  6. We are two simplified fractions. The LCD is 9 and the numerator of one of the fractions is the answer of 2*5*8*3*5+1-1+1-1+1-1+3-6/2 divided by 25*3*2. The numerator of both fractions are consecutive integers. The denominator are the same. The denominator of the second fraction is 3 divided by 1/3. The second fraction is less then then the first. Who are we?

  21. The LCD of 2 simplified fractions (not a mixed number or an improper fraction) is the product of 3 and 5. The smaller denominator is the first fraction and the bigger denominator is the second fraction. The first fraction has a difference of 2 when you subtract the numerator and the denominator. The second fraction is less than 50% but more than 20%. The difference of the two denominators is 2. The difference of the two numerators 1. Who are we?
