Question

1.26×3/4+0.74÷4/3-75%简便计算

Answer 1

利用乘法分配律计算
1.26×3/4+0.74÷4/3-75%
=1.26×3/4+0.74×3/4-75%
=1.26×0.75+0.74×0.75-0.75
=0.75×(1.26+0.74-1)
=0.75×1
=0.75

Answer 2

1.26×3/4+0.74÷4/3-75%的简便计算:
1.26×3/4+0.74÷4/3-75%
=1.26×3/4+0.74×3/4—3/4
=1.26×3/4+0.74×3/4—1×3/4
=（1.26+0.74—1）×3/4
=1×3/4
=3/4

Answer 3

1. 抓住他这个3/4，后面的除以4/3就等于乘以3/4，75%就是3/4，即1*3/4，
2. 提取3/4，原算式就相当于（1.26+0.74-1）*3/4
3. 答案一目了然，3/4

Answer 4

利用乘法分配律
1.26×3/4+0.74÷4/3-75%
=1.26×3/4+0.74×3/4-3/4
=（1.26+0.74-1）×3/4
=1×3/4
=3/4

Answer 5

1.26*3/4+0.74/4/3-75%
=1.26*3/4+0.74*3/4-3/4
=(1.26+0.74-1）*3/4
=1*0.75
=0.75

追答

1.26*3/4+0.74/4/3-75%
=1.26*3/4+0.74*3/4-3/4
=(1.26+0.74-1）*3/4
=1*3/4
=3/4
