There are an infinite number of them. 2/3, 3/4, 3/5, 5/8, 7/8, 15/16.... Any fraction where the denominator (bottom number) is greater than the numerator (top number), AND the denominator is less than twice the numerator. So for example 2/3 above. Numerator = 2, denominator = 3 which is less than 2. Twice 2 is 4, and 3 < 4.
3*(n - 5) = 2*n + 11
