If you want fractions that are similar to the two fractions you have:
Because the fractions are already in their simplest form, you can continue to multiply the numerator (top number) and the denominator (bottom number) by two (one whole), which is represented by 2/2.
1/6 = 2/12 = 4/24...
1/9 = 2/18 = 4/36...
If you want to have the same value for each fraction but have the same denominator:
(1/6)(9/9) = 9/54
(1/9)(6/6) = 6/54
