乘加是什么意思

34*56=34*(6+50)=34*6+34*50

(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

十五分之八乘四分之三加二分之一加五分之三 =8/15×3/4+1/2+3/5 =2/5+3/5+1/2 =1+1/2 =3/2 (27/1+9/1)×54 =2+6 =8 5—9/2除以27/8—4/1 =5-2/9÷8/27-1/4 =5-3/4-1/4 =4 8/7除以7/4减8/3除以7/4 =7/8÷4/7-3/8÷4/7 =7/8×7/4-3/8×7/4 =7/4*(7/8+3/8)...

3.4*9+3.4=3.4*10=34

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.

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

3.28×37+6.4×32.8-3.28 =3.28×37+64×3.28-3.28 =3.28×(37+64-1) =3.28×100 =328

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...
