    Answer:

    – 35 / 8 = -4  3/8

    Step-by-step explanation:

    = ( 13 / 5 + ( -5 ) / 10 ) / ( ( -3 ) / 7 * 4 / 5 )

    Reduced -5/10 to its simplest form

    = ( 13 / 5 + ( -1 ) / 2 ) / (( -3 ) / 7 * 4 / 5 )

    LCM of 5 and 2 = 10

    = ( 2 * 13 + 5 * -1 / 10 ) / ( -3 * 4 / 7 * 5)

    = ( 26 + ( -5 ) / 10 ) / (( -12) / 35 )

    = ( 21 / 10 ) / ( ( -12) / 35 )

    = ( 21 / 10 ) * ( ( – 35 ) / 12 )

    = 7 * – 5 / 2 * 4

    = – 35 / 8 = -4  3/8
