    Answer:

    Step-by-step explanation:

    Given:

    27 + 2/3 ÷ 3 + 9/10

    In division, compatible numbers are numbers that can be divided mentally.

    27 + 2/3 ÷ 3 + 9/10

    27 + 0.67 ÷ 3 + 0.9

    27.67 ÷ 3.9

    = 7.0948717948717

    Approximately

    = 7

    But, alternatively

    27.67 ÷ 3.9

    27.67 is closer to 28

    3.9 is closer to 4

    Therefore,

    28 ÷ 4

    = 7

    The quotient of 27 + 2/3 ÷ 3 + 9/10 using compatible numbers is around 7
