✔ 最佳答案
1.{ (-1/4)+3/4*2/3+(-1/4)} ÷ 12*2/5Solve
{ (-1/4)+3/4*2/3+(-1/4)} ÷ 12*2/5
= {(-1/4)+ 1/2 + (-1/4)} * 24/5
= {(-2/4) + 2/4} * 24/5
= 0
2.{(-6/4)*10/2*(-2/3) }÷5/3*1/10
Solve
{(-6/4)*10/2*(-2/3) }÷5/3*1/10
= -5 ÷ (1/6)
= -30

1.{ (-1/4)+3/4*2/3+(-1/4)} ÷ 12*2/5
={ (-1/4)+1/2 +(-1/4)} ÷ 24/5
=0 ÷ 24/5
=0
2.{(-6/4)*10/2*(-2/3) }÷5/3*1/10
={(-6/4)*10/2*(-2/3) }÷1/6
=[(-3/2) * 5 * (-2/3)] *6
=30
={ (-1/4)+1/2 +(-1/4)} ÷ 24/5
=0 ÷ 24/5
=0
2.{(-6/4)*10/2*(-2/3) }÷5/3*1/10
={(-6/4)*10/2*(-2/3) }÷1/6
=[(-3/2) * 5 * (-2/3)] *6
=30
