Question

7. Determine cada quociente a seguir. • -40 : (-20) • 40 : ( -20) • -40 : 20 • 40 : 20 • -400 : (-7) • +400 : (+20) • -400 : (-20) • 400 : (-20)

Answer 1

Resposta:

• -40 ÷ (-20) = 2

• 40 ÷ (-20) = -2

• -40 ÷ 20 = -2

• 40÷20=2

• -400÷(-7)= 57,142 (inexata)

• 400÷20= 20

• -400÷-20= 20

• 400÷-20= -20

Explicação passo-a-passo:

Answer 2

Resposta:

-40 : (-20) = +2

+40 : ( -20) = -2

-40 : 20 = -2

+40 : 20 = +2

-400 : (-7) = + 57,14285...

+400 : (+20) = +20

-400 : (-20) = +20

+400 : (-20)= -20
