    Siti bought 13 blue buttons

    Step-by-step explanation:

    for not to get confused, we are going to solve the problem step by step

    Siti had 135 buttons

    5/9 of the buttons were red and the rest were blue

    let's calculate how many buttons were red out of 135

    135 * 5/9 = 75

    if 75 buttons were red and the rest were blue, we can calculate how many were blue

    135 - 75 = 60

    says she only use 64 red buttons

    if we had 75 red buttons and she used 64

    75 - 64 = 11

    she tells us that she had 84 buttons left, from which we know she had 11 red buttons that had been left over and 60 blue ones that she did not use, so we can calculate how many blue buttons she bought since we have the total number of buttons that she has now

    84 - 60 - 11 = 13

    Siti bought 13 blue buttons
