17.5×18坚式计算答案

17.5×18=315,其竖式计算过程如下:

(1)17.5÷12.5×1.4,=1.4×1.4,=1.96;(2)1.58×99+1.58,=1.58×(99+1),=1.58×100,=158;(3)4.38÷0.125÷8,=4.38÷(0.125×8),=4.38÷1,=4.38;(4)6.4×4.5+3.6×4.5,=(6.4+3.6)×4.5,=10×4.5,=45.

17+5×6 =17+30 =47 你好,本题已解答,如果满意 请点右上角“采纳答案”。

17.5÷0.25×0.4 =70×0.4 =28 按运算顺序计算

脱式计算 17-(5/11-9分之2) =17-23/99 =16又76/99

4.38x10.1 =4.38x(10+0.1) =4.38x10+4.38x0.1 =43.8+0.438 =44.238

17.5÷1.25÷0.08脱式计算 =17.5÷(1.25x0.08) =17.5÷0.1 =175

75+5x=1750 15+x=350 x=350-15=335

17.5-6.3+3.7 =11.2+3.7 =14.9

(1)36÷〔(56-13)×3〕,=36÷〔12×3〕,=36÷32,=24;(2)17.5-5(x+0.5)=9x, 17.5-5x-2.5=9x, 15-5x=9x, 15-5x+5x=9x+5x, 14x=15, 14x÷14=15÷14, x=1514;(3)(87.2+87.2+87.2×2)×25,=87.2×(1+1+2)×25,=87.2×4×25,=87.2×(4×...
