34.3乘加 2.6加5.4乘3.2 1.2乘(9.6除以2.4)除以4...

(1×2×3+2×4×6+3×+6×9)/(1×3×5+2×6×10+3×9×15) =【1×2×3×(1+2+3)】/【1×3×5×(1+2+3)】 =(1×2×3)/(1×3×5) =2/5

3O加31加32加33加34加32乘95的简便运算 3O加31加32加33加34加32乘95 =30+31+32+33+34+32*95 =(30+34)+(31+33)+32+32*95 =32*(2+2+1+95) =32*100 =3200

你好,很高兴为你解答 1/6÷[9/17x(3/4+2/3)] =1/6÷(9/17x17/12) =1/6x4/3 =2/9(表示9分之2) 满意采纳哦!

9.99×2.22+3.33×3.34 =3.33×6.66+3.33×3.34 =3.33×(6.66+3.34) =3.33×10 =33.3

78×3+78×3+6×22 =78×3×2+6×22 =78×6+22×6 =6×(78+22) =6×100 =600

9.9乘22.2加33.3乘3.34 =9.9x2x11.1+11.1x3x3.34 =11.1x19.8+11.1x10.2 =11.1x(19.8+10.2) =11.1x30 =333 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...

(1).-1/3

2.6*1.5+0.15*3.4 ? =2.6*1.5+1.5*0.34 =1.5*(2.6+0.34) =1.5*2.94 =1.5*3-1.5*0.06 =4.5-0.09 =4.41

解:依题意得算式, 20-16÷4+3×2 =20-4+6 =22 答:20减去16除以4的商,所得的差加上3与2的积,和是22.

3.4*9+3.4=3.4*10=34
