Question

用自己喜欢的方法计算

1.6/(0.375*5分之4+8分之1*0.8) 列出算式

Answer 1

1.6/(0.375*5分之4+8分之1*0.8)
=8/5÷（3/8*4/5+1/8*4/5）
=8/5÷{4/5*(3/8+1/8)}
=8/5*5/4*2
=4

1.6/(0.375*5分之4+8分之1*0.8)
(8/5)/(375*4/5000+(1/8)*(8/10))
=(8/5)/(3/10+1/10)
=(8/5)/(2/5)
=4

1.6/(0.375*5分之4+8分之1*0.8)
1.6/(0.375*4/5+1/8*0.8)
=1.6/(1.5/5+0.1)
=1.6/(0.3+0.1)
=4

Answer 2

1.6/(0.375*4/5+1/8*0.8)
=1.6/(1.5/5+0.1)
=1.6/(0.3+0.1)
=4

Answer 3

=8/5÷（3/8*4/5+1/8*4/5）
=8/5÷{4/5*(3/8+1/8)}
=8/5*5/4*2
=4

Answer 4

(8/5)/(375*4/5000+(1/8)*(8/10))
=(8/5)/(3/10+1/10)
=(8/5)/(2/5)
=4
