    2/3 = 14/21 ... red beads ... 4/21 blue beads ... 14+4 = 18/21 ... so you need 3/21 more to finish the necklace and 3/21=1/7 in white beads

    2/3 - Red

    4/21 - Blue

    Change the red fraction so both fractions will have the same denominator

    2/3 change to 14/21

    Add blue and red together

    14/21 + 4/21 = 18/21

    Then subtract it from the total to get the white beads

    21/21 - 18/21 = 3/21

    Simplify it to get 1/7

    Ans : 1/7
