六年级上册每天10道计算题及答案
(1)2.64×1.7-2.64×0.7 =2.64×(1.7-0.7) =2.64×1 =2.64
(2)31.5×1.07-3.15×0.7 =3.15×10.7-3.15×0.7 =3.15×(10.7-0.7) =3.15×10 =31.5
(3)2.7×5.7-2.7+5.3×2.7 =2.7×(5.7-1+5.3) =2.7×10 =27
(4)0.625÷0.125×0.8
=(0.625×0.8)×8÷(0.128×8) =0.5×8÷1 =4
(5)18.6×6.1+3.9×18.6 =18.6×(6.1+3.9) =18.6×10 =186
(6)1.3579+3.5791+5.7913+7.9135+9.1357 =(1+3+5+7+9)×1.1111 =25×1.1111 =27.7775
(7)52.5x2.9+5.45 =5.25x29+5.25+0.2 =5.25×(29+1)+0.2 =5.25×30+0.2 =157.5+0.3 =157.7
(8)0.92x15+0.08x15 =(0.92+0.08)×15 =1×15 =15
(9)0.72×1.25×2.5 =0.9×(0.8×1.25)×2.5 =0.9×1×2.5 =2.25
(10)400.6x7-2003x0.4 =200.3x14-200.3x4 =200.3×(14-4) =200.3×10
=2003
(11)[3/4-7/8/(5/6+4/5)]*28 =[3/4-7/8÷49/30]*28 =[3/4-15/28]*28 =3/4*28-15/28*28 =21-15 =6
(12)(1.25*4/5-0.76)/(1又3/8+1又1/40) =(1-0.76)/2.4 =0.24/2.4 =0.1
