3.75×4.8+62.5×0.48=3.75×4.8+6.25×4.8=4.8×(3.75+6.25)=4.8×10=48
7.5×0.48+4.8×0.25＝7.5×0.48+0.48×2.5＝0.48x(7.5+2.5)=0.48x10=4.8
0.48×7.6+0.24×4.8=4.8*0.1*7.6+0.24×4.8=4.8*0.76+0.24×4.8=4.8*(0.76+0.24)=4.8*1=4.8
4.8*0.23+0.48*7.7=4.8*0.23+4.8*0.77=4.8*（0.23+0.77）=4.8
4.8×0.9+4.8×0.1=4.8×（0.9+0.1）=4.8
1.2×(4×0.25）=1.2×1=1.2
=98*0.48+0.48=(98+1)0.48=99*0.48=(100-1)*0.48=48-0.48=47.52
3.75x4.8+62.5x0.48=4.8x（3.75+6.25）=4.8x10=48
4.5×10.1=4.5×（10+0.1）=4.5×10+4.5×0.1=45+0.45=45.450.125×25×32=0.125×25×8×4=（0.125×8）×（25×4）=1×100=10
6.3×10.1=6.3×(10+0.1)=6.3×10+6.3×0.1=63+0.63=63.63再问：7.3*9.9的简便计算再答：7.3×9.9=7.3×(10-0.1)=7.3×10-7.3×
9.9乘以4.8+0.48=9.9x4.8+0.1x4.8=(9.9+0.1)x4.8=10x4.8=48
3.75×4.8+6.35×4.8-4.8×0.1=4.8×（3.75+6.35-0.1）=4.8×10=48
10.1*4.8-0.48=(10+0.1)*4.8-0.1*4.8=10*4.8=48
（44.6-42.8）÷（3.62+2.38）=1.8÷6=0.34.8*9.9+0.48=4.8*9.9+4.8*0.1=4.8*（9.9+0.1）=4.8*10=48
4.8先除以0.48得到10再用10乘以9.2得到92
原式=6.3*（10+0.1）=6.3*10+6.3*0.1=63+0.63=63.63
3.75×4.8+62.5×0.48=3.75×4.8+6.25×4.8=4.8×(3.75+6.25)=4.8×10=48
5.12*10+5.12*0.1=51.2+0.512=51.712
0.12*（4*0.25）0.009*（8*1.25）
＝2.25*4.8+7.75*4.8再答：＝4.8*＜2.25+7.75＞再答：＝4.8*10再答：＝48再问：谢谢啦再答：满意的话要采纳哦再问：那54.÷1.8+46怎么做再答：额(⊙o⊙)…你等一
