计算下列算式,要求简便4.25×5.24+1.52×2.51
计算下列算式,要求简便
4.25×5.24+1.52×2.51
计算下列算式,要求简便4.25×5.24+1.52×2.51
原式=4.25×5.24＋1.52×2.51
=(4+0.25)×(5+0.24)+(1+0.52)×(2+0.51)
=20+0.96+1.25+0.06+(2+0.51+1.04+0.2652)
=22+3.82+0.2652
=26.0852
(*^__^*) 嘻嘻~!希望帮到你哦~!
4.25*5.24+1.52*2.51
=(4+0.25)×(5+0.24)+(1+0.52)×(2+0.51)
=20+0.96+1.25+0.06+(2+0.51+1.04+0.2652)
=22+3.82+0.2652
=26.0852
