7.29乘4.6加46乘1.271=0.729×46+46×1.271=(0.729+1.271)×46=2×46=929.6乘3.6加8.2乘0.2=9.6×9×0.4+4.1×0.4=(9.6×9

0.9乘8.4加1乘0.84=9×0.84+0.84=（9+1）×0.84=10×0.84=8.472乘1.25=9*（8*1.25）=9*10=900.36乘2.4加76乘0.036=0.36×2.

（38）×49+72×51+34×49=7200.

第一题：1.98*51-199.8*19+1998*0.82=1.98*51-199.8*(19-8.2)=1.98*51-199.8*10.8=100.98-2157.84=-2056.86第二题：

49*49+49*51=49*(49+51)=49*100=4900

3.6×98+36×0.2=36×9.8+36×0.2=36×（9.8+0.2）=360如果本题有什么不明白可以追问,

2.35＊2＊99+4.7=4.7*(99+1)=470

51等于乘 + 乘

2*3+5*9行不?

用计算机一下就出来了.或者换成分数、14/5*6/518/5*6/5=206/25*代表乘以

5.1乘3.6加2.1乘3.6加7.2乘6.4=3.6x(5.1+2.1)+7.2x6.4=3.6x7.2+6.4x7.2=7.2x10=72

=6.27×3.6+3.78×10×0.36=6.27×3.6+3.78×3.6=(6.27+3.78)×3.6=10.05×3.6=(10+0.05)×3.6=10×3.6+0.05×3.6=36+

1.原式=3.6*4.7+3.6*5.1+3.6*0.2=3.6*（4.7+5.1+0.2）=3.6*10=362.原式=1.2*3.8+1.2*3.8+1.2*24=1.2*（3.8+3.8+24）

3.6*3.8+36*0.72=36*0.38+36*0.72=36*（0.38+0.72）=36*1.1=36+3.6=39.6

3.6×11.1+1.2×66.7=1.2×3×11.1+1.2×66.7=1.2×(33.3+66.7)=1.2×100=1207.2×14.5+17×2.8=(10-2.8)×14.5+17×2.

49*51+(451*26+25*451)=49*51+51*451=51*500=25500

3.6乘2.4+0.36乘58+0.18乘36=3.6×2.4+3.6×5.8+3.6×1.8=3.6×(2.4+5.8+1.8)=3.6×10=36

原式=48×(23+26+51)=48×100=4800

寒樱暖暖为你4.8×2.8+9.6×3.6=4.8×2×1.4+9.6×3.6=9.6×1.4+9.6×3.6=9.6×（1.4+3.6）=9.6×5=48（或在客户端右上角评价点【满意】）是我前进的
