(0.8+0.8+0.8+0.8×2)×1.25
=(0.8×1.25)+(0.8×1.25)+(0.8×1.25)+(0.8×1.25)+(0.8×1.25)
=1+1+1+1+1
=5
0.1÷0.001×(100.1-1.001)
=100×(100.1-1.001)
=100×100.1-100×1.001
=10010-100.1
=9909.9
(0.8+0.8+0.8+0.8×2)×1.25
=0.8(1+1+1+2)×1.25
=0.8×5×1.25
=0.8×1.25×5
=1×5=5
0.1÷0.001×(100.1-1.001)
=100×1.001×(100-1)
=100.1×99
=9909.9
(-0.8)+1.2+(-0.7)+(-2.1)+0.8+3.5等于多少,一定采
(12.5+1.25)×0.8简便计算.
0.8+0.88= 0.8+0.88+0.888= 0.8+0.88+0.888+0.8888= 0.8+0.88+0.888+0.8888+……+0.8888888=0.8+0.88=0.8+0.88+0.888=0.8+0.88+0.888+0.8888=0.8+0.88+0.888+0.8888+……+0.8888888=

5.6 ÷0.8+2.4 ÷0.8的计算过程
0.8×(12.5+1.25)的简便计算
2.46×0.8+1.23×0.4 简算
x+0.8×(12-x)=10
x+(0.8+1/5)=2.5
0.2+0.4+0.6+0.8+0.10+0.12+0.14+……+0.98(用最简便的方法计算)
1.25×17.6+36.1÷0.8+2.63×12.5
1.25×17.6+36.1÷0.8+2.63×12.5
1.25×17.6+36.1÷0.8+2.3×12.5
0.1×0.2×0.4+0.2×0.4×0.8+0.3×0.6×1.2)分之(0.1×0.3×0.9+0.2×0.6×0.8+0.3×0.9×2.7)
(0.1×0.2×0.4+0.2×0.4×0.8+0.3×0.6×1.2)分之(0.1×0.3×0.9+0.2×0.6×0.8+0.3×0.9×2.7)=
一道脱式计算.0.8×2.6+4/5×6.4+0.8
