32.5×2.9 3.45脱式计算.

32.5×0.99+0.35 =32.5x1 -32.5x0.01+0.35 =32.5 -0.325+0.35 =32.5 +0.025 =32.525

(1)32.5+1.07+17.5+0.93=(32.5+17.5)+(1.07+0.93)=50+2=52;(2)32×125×25=4×8×125×25=(8×125)×(25×4)=1000×100=100000;(3)1119-219-419=919-419=519.

=45.6x(32.5+63.8+1) =45.6x97.3 =4436.88

3.25剩47加5.3剩32.5 =3.25x47+3.25x53 =3.25x(47+53) =3.25x100 =325 请采纳正确答案,你们只提问,不采纳正确答案,回答都没有劲!谢谢管理员推荐采纳!! 朋友,请【采纳答案】,您的采纳是我答题的动力,如果没有明白,请追问。谢谢。

0.25×32×12.5 =0.25×(4×8)×12.5 =(0.25×4)×(8×12.5) =1×100 =100

请把题目写清楚

4.32×0.45 =4.32×5×0.09 =21.6×0.09 =1.944

62除以4乘2 =15点5乘2 =31

(1)5.5×17.3+6.7×5.5=5.5×(17.3+6.7)=5.5×24=132;(2)1.5×105=1.5×(100+5)=1.5×100+1.5×5=150+7.5=157.5;(3)9.07-22.78÷3.4=9.07-6.7=2.37;(4)3.8+4.29+2.1+4.2=(3.8+4.2)+(4.29+2.1)=8+6.39=14.39;(5)2.65×1.7+1.35×1.7=...
