To find the common denominator of 1/3 and 1/4, place an orange and yellow piece beside each other in a Fraction Ring. Find an interval that aligns with the start and end points of the orange and yellow pieces. Intervals of 1/12 align with the start and end points of the orange and yellow pieces, so 12 is a common denominator of 1/3 and 1/4.
