  1. Answer:

    Step-by-step explanation:

    :(-5/9÷20/36) + (-13/14×28/39) – (7/11÷21/44)÷-4/15​=

    (-5/9*36/20) + (-13/14×28/39) – (7/11 * 44/21)/-4/15=

    -1/1+(-2/3)-(7/11*44/21)/-4/15=

    -1/1+(-2/3)-4/3/(-4/15)=

    -1/1-2/3-4/3*15/-4=

    -1/1-2/3-5/1=

    -3-2/3 -5/-1=

    -5/3-5/(-1)=

    (-5)/3-(-1)/5= -25-(-3)/15= -25+3/15= -28/15 or -1whole13/15.

    please mark as a brain list.

    (and not thanks only brain list also ok bro/sis.)
