    Let us assume that the number of days she practiced the piano to be "d"

    Since she practiced 2/3 hours a day, the total number of hours would be: 2/3*d

    Now we are given the total number of hours during summer that she practiced be be equal to 32/23

    So we equate 2/3 * d to 32/23 to find d

    2/3*d = 32/23

    d = (32/23) / (2/3)

    d = (32/23) * (3/2)

    d = 48/23 hours

    The equation that can be used to find the number of days that she practiced piano during the summer is 2/3*d = 32/23
