  1. Answer:

    a)10 d) 10 g) 18 b)-8 e)7.2 c)10 = (-2) f)3

    Step-by-step explanation:

    a)90 ÷ [(-5) + (-4)]= 90 ÷ [-9]

    =10

    (d) (57 – (-3)÷ [(-60) ÷ 10])= [60÷(-6)]

    =10

    (g) (-25) – (-7)] ÷[(-2)-(-1)]= -18÷-1

    =18

    (b) (-64) ÷[6-(-2)] = (-64) ÷8

    = -8

    (e) (12-48) ÷ 1-6) = -36÷ (-5)

    = 7.2

    (c) [{40 ÷ (-4)} = (-2)] = 10 = (-2)

    (f) (-63) ÷ [(-20) + (-1)]​ = (-63) ÷ (-21)

    = 3​

    Please mark me as brilliant
