54.5%1.36 45.5%2.64用简便方法计算

96

2.64x101-2.64 =2.64x(101-1) =2.64x100 =264

7.36*0.25+2.64/4=7.36*0.25+2.64*1/4=(7.36+2.63)*0.25=10*0.25=2.5

(1)3.58-2.36-(2.64-1.42)=3.58-2.36-2.64+1.42=(3.58+1.42)-(2.36+2.64)=5-5=0;(2)(1 4 +1 6 ?1 3 )*12=1 4 *12+1 6 *12-1 3 *12=3+2-4=1;(3)3.6*11 8 +8.4÷8 11 =3.6*11 8 +8.4*11 8 =(3.6+8.4)*11 8 =12*11 8 =33 2 ;(4)3 4 ÷[3.75*(1.2?1 5 )]=3 4 ÷[3.75*1]=3 4 ÷33 4 =1 5 .

14.84-1.36+1.16-2.64=(14.84+1.16)-(2.64+1.36)=16-4=12*************************************************************** ^__^真心祝你学习进步,如果你对这个答案有什么疑问,请追问,另外如果你觉得我的回答对你有所帮助,请千万别忘记采纳哟!***************************************************************

14.84-1.36+1.16-2.64=(14.84+1.16)-(2.64+1.36)=16-4=12

2.64-1.73+5.36-4.27=2.64+5.36-1.73-4.27=8-(1.73+4.27)=8-6=22.64+1.73+5.36+4.27=(2.64+5.36)+(1.73+4.27)=8+6=14谢谢,请采纳

7.64-4.99=7.64-5+0.01=2.64+0.01=2.65

原式=2.64*(51.9+100*0.481)=2.64*(51.9+48.1)=2.64*100=264祝你心想他天天向上,加油!
