a(-4/5 × (2/8) b -7/3 ÷ (-8/3) c 4/7 × (2/9) ÷ (-3/6 d ( -8/9 × (-4/3) ÷ (3/9) e (2/9 ×5/3) ÷ (2/4 × 8/3)

Answer 1

Respuesta:

Utilizaré el asterisco como símbolo de la multiplicación.

Explicación paso a paso:

A) -4/5 * 2/8

=> (4*-1)/5*2/(4.2)

Tacha el 4 y quedará:

=> -1/5 <> -0.2

B) -7/3 ÷ -8/3

=>  -7/3 * 3/-8

=> (-7*3)/(3*-8)

=> -21/-24

Sacamos tercia

=> -(-21/24)

=> 7/8 <> 0.9

C) 4/7*2/9÷-3/6

=> (4*2*6)/(7*9*-3)

=>48/-189

Movemos el símbolo negativo a la izquierda

=> -48/189 => -16/63 <> -0.25

D) -8/9*-4/3÷3/9

=> -(8*-4-9)/(9*3*3)

=> -(-288/81)

Simplifica

=> -(-32/9) => 32/9 <> 3.56

E) (2/9*5/3)÷(2/4*8/3)

=> (2*5/9*5)÷(2*8/4*3)

=> 10/27÷(1*8/2*3)

=> 10/27÷8/6

=> 10/27*6/8

=> 10*6/27*8

=> 60/216

Simplificar

=> 5/18 <> 0.28
