75x4x25x4怎么用脱式计算?

75x4x25x4 =(75x4)x(25x4) =300x100 =30000

(125x25)x4 =125×(25×4) =125×100 =12500

(20+4)x25 =24x25=600 先算括号里的,再算乘法 望采纳

125x28x40x25 =125x40x28x25 =125x(8x5)x(7x4)x25 =(125x8)x(5x7)x(4x25) =1000x35x100 =3500000

96x25 =24x4x25 =24x100 =2400 朋友,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!!! 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。

(0.4+4)×25 =0.4×25+4×25 =10+100 =110

104×25用脱式计算两种方式 第一种: 104x25 =(26x4)x25 =26x(4x25) =26x100 =2600 第二种: 104x25 =(100+4)x25 =100x25+4x25 =2500+100 =2600

简便计算 乘法分配率 (80-8)x25 =80x25-8x25 =2000-200 =1800 望采纳 谢谢

125x25x8x8=(125x8)x(25x8)=1200 [49十(31X56)]除以7 =49÷7+31X56÷7 =7+31X8 =7+248 =255

136x25-25x36 =25x(136-36) =25x100 =2500 望采纳
