脱式计算
(1)原式
=3/4x5/7x4/3-1/2
=3/4x4/3x5/7-1/2
=5/7-1/2
=3/14
(2)原式
=3.14x16-3.14x6
=3.14x(16-6)
=3.14x10
=31.4
(3)原式
=10-1/5+(35%-1/10)x1/5
=10-0.2+(0.35-0.1)x1/5
=10-0.2+0.25x1/5
=9.8+0.05
=9.85

1.统一化成分数计算=3/14
2.=3.14*16-3.14*6
=3.14*(16-6)
=3.14*10
=31.4
3.=10-[0.2-(0.35-0.2)*0.2]
=10-[0.2-0.15*0.2
=10-[0.2-0.03]
=10-0.17
=9.83请你帮我写一下这题行吗12/...
