Question

Calculae A/B, si: A= (6/10) *( -5/18) *( -3/20)
B= (-16/27) * (-81/125) * (-25/64)

Answer 1

A = (6/10) *( -5/18) *( -3/20)
A= 6×(-5)×(-3) / 10×18×20
A = 90/ 3600 mitad
A = 45/ 1800 tercera
A = 15 / 600 tercera
A = 5/ 200 quinta
A = 1/40

B = (-16/27) * (-81/125) * (-25/64)
B = (-16)×(-81)×(-25)/ 27×125×64
B = - 32400/ 216000 mitad
B = - 16200/ 108000 mitad
B = - 8100 / 54000 mitad
B = - 4050/ 27000 mitad
B = -2025/ 13500 quinta
B = -405 /2700. Quinta
B = - 81 / 540 tercera
B = - 27 / 180 tercera
B = -9 / 60 tercera
B = - 3/20

Calcular A/B


A/B = 1/40 / - 3/20
= 1×20 / 40×(-3)
= 20 / - 120
= - 1/6
