B) (8 × 7 + 5 × -8) ÷ -4 =​

Answer 1

Respuesta:

A) 9/7

B) 4

Explicación paso a paso:

A) 45 ÷ {-2 + 12 ÷ (-7 + 3) + 12 -[-24 ÷ -3×5+ 7] + 5}

45 ÷ {-2 + 12 ÷ (-7+3) + 12 -[8×5+ 7] + 5}

45 ÷ {-2 + 12 ÷ (-7 + 3) + 12 -[40+ 7] + 5}

45 ÷ {-2 + 12 ÷ (-4) + 12 -[47]+ 5}

45 ÷ {-2 + (-3) + 12 - 47 + 5}

45 ÷ { -5 + 12 -47 +5 }

45 ÷ ( +7 - 47 + 5)

45 ÷ ( -40 + 5 )

45 ÷ ( - 35)

9 ÷ 7 ----> 9/7

B) (8 × 7 + 5 × -8) ÷ -4

( 56 + 5 × -8 ) ÷ -4

( 56 + (-40)) ÷ -4

( 56 -40) ÷ 4

16 ÷ 4

4
