计算题：3-7.14/3.5*1.05和【20-（90.75/6.6+2.25）】*11.6用脱式
6.6.
4.5=x×2.25％×20％
6.6+0.6×20+0.×19 简便运算
12/11x-20%=6.6
2.25×0.16+264×0.0225+5.2×2.25+0.225×20等于多少?
2.25*0.16+264*0.0225+5.2*2.25+0.225*20=
2.25*0.16+264*0.0225+5.2*2.25+0.225*20
90.75除以3.3等于多少?
2.5%X+(20-X)*2.25%=0.485
x+x*2.25%*(1-20%)=1527
90.75除以3.3竖式计算
（90.75）10转化成八进制
