    I so wanted to answer this question.

    However, my answer is "Anonymous" as your post is Anonymous. There is no need for an Anonymous question in this category,

  • (21 - 23) / 3 = -2/3 = -0.66666666.... = -0.67

    (27 - 23) / 3 = 4/3 = 1.33333.... = 1.33

    0.2514 and 0.9082

    0.9082 - 0.2514 =>

    0.6568

    There are 30 days in June

    30 * 0.6568 =>

    3 * 6.568 =>

    19.5 + 0.204 =>

    19.704

    20 days
