    28 beads were used to make the bracelet. 7 beads were not yellow.

    Step-by-step explanation:

    3/4 beads used to make the bracelet are yellow

    If 21 beads are 3/4 of the bracelet and yellow

    1/3 of the 21 beads would be 1/4 of the bracelet

    7 beads are 1/3 of 21 beads

    7 * 4 = 28 beads
