16.25+(6.72-4.25)-3.72=(16.25-4.25)+(6.72-3.72)=12+3=15
4.25*5.24*1.52*2.51=4.25*8*0.19*1.31*4*2.51=34*0.19*1.31*10.04=6.46*1.31*10.04=8.4626*10.04=84.626+0
4.25*4=174.25*5.24*1.52*2.51=(4.25*4)*1.31*1.52*2.51=17*1.31*1.52*2.51=84.964504再问：4.25*4=17？是什么？答案正
=(3.75+4.25)+(2.10-1.10)=8+1=9
=4.25*4*9.9/(2.5*4)+0.17=17*9.9/10+0.17=1.7*9.9+1.7*0.1=1.7*(9.9+0.1)=1.7*10=17
4.25+2.67-0.67+5.75=4.25+5.75+2.67-0.67=10+2=12
4.25×101-4.25=4.25x(100+1)-4.25=4.25x100=425
4.25-(18.1-15.27)=4.25+15.27-18.1=19.52-18.1=1.423.84-2.9+2.16-3.1=(3.84+2.16)-(2.9+3.1)=6-6=0再问：17.
1/8×5.75+1.25×4.2=0.125×5.75+1.25×4.2=0.125×（5.75+10×4.2）=0.125×47.75=5.96875
24.8-4.8*4.25=4.44.25*9.8+0.85=52.5
4.25*0.99+0.01=4.25*(1-0.01)+0.01=4.25+0.01*(1-4.25)=4.25-0.01*3.25=4.25-0.0325=4.2175
4.25×0.75+75%+4.75+0.75=4.25×0.75+0.75×1+4.75+0.75=4.25×0.75+1×0.75+4.75+0.75=0.75×（4.25+1+4.75）=0.7
5.75加4.25乘2加78=5.75+8.5+78=14.25+78=92.250.75乘18÷0.15减6.8=0.75÷0.15×18-6.8=5×18-6.8=90-6.8=83.4
再答：给个釆纳，新年快乐再问：祝你新年快乐
解题思路：化简小括号后，变为依次大1/2的等差数列。问题可求。解题过程：varSWOC={};SWOC.tip=false;try{SWOCX2.OpenFile("http://dayi.prced
15.7-3.75-4.25=15.7-（3.75+4.25）=15.7-8=7.7
1.75/0.5+4.25*2=1.75*2+4.25*2=(1.75+4.25)*2=6*2=12
1.75/0.5+4.25*2=1.75*2+4.25*2=2*(1.75+4.25)=2*6=121.75/0.5就是乘于1/2的倒数就是2
57.5-4.25-15.75=57.5-(4.25+15.75)=57.5-20=37.5
