3.25除以12.5除以0.8的脱式计算

3.25除以12.5除以0.8的脱式计算 3.25除以12.5除以0.8 =3.25÷(12.5*0.8) =3.25÷10 =0.325

300÷12 =300÷3÷4 =100÷4 =25

0.35×1.6+0.35×3.4 0.25×8.6×4 6.72-3.28-1.72 0.45+6.37+4.55 5.4+6.9×3-(25-2.5)2×41846-620-380 4.8×46+4.8×54 0.8+0.8×2.5 1.25×3.6×8×2.5-12.5×2.4 28×12.5-12.5×20 23.65-(3.07+3.65)

504/((8+5)*(3-25)) =504/(13*(-22)) =504/(-286) =-252/143 =-1.76 望采纳,谢谢!

(1)2.25×1.8+12.5×0.18=(2.25+1.25)×1.8=4×1.8=7.2;(2)7.28-(1.28+0.25)=7.28-1.28-0.25=6-0.25=5.75;(3)2÷85×2524=2×58×2524=12596;(4)[1-(13-14)]×24=1×24-(13×24-14×24)=24-(8-6)=24-2=22;(5)3.68-0.82-0.18=3.68-(...

125x(8 +25分之3) =125×8+125×3/25 =1000+15 =1015

28/15

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。
