15.52%1.6×5%5.52的计算

15.52-1.6*5-5.52=15.52-8-5.52=15.52-5.52-8=10-8=2

15.52-1.6*5-5.7=15.52-8-5.7=15.52-13.7=1.82

15.52-1.6*5-5.52=15.52-5.52-1.6*5=10-1.6*5=2*5-1.6*5=5*(2-1.6)=5*0.4=2也可用上面那位朋友的方法,一定要简便方法,不妨用我这种,谢谢.

(1)15.52-1.6*5-5.7,=15.52-8-5.7,=7.52-5.7,=1.82;(2)9.83*1.5+6.17*1.5,=1.5*(9.83+6.17),=1.5*16,=1.5*2*8,=24;(3)19.8-0.6*0.6-0.64,=19.8-0.36-0.64,=19.8-(0.36+0.64),=19.8-1,=18.8;(4)0.125*7.9*8,=0.125*8*7.9,=1*7.9,=7.9;(5)63*10.1,=63*(10

15.52-1.6*5-5.2=15+0.52-8-5-0.2=(15-5-8)+(0.52-0.2)=2+0.32=2.32

15.52-1.6*5-5.7=15+0.52-1.6*5-5-0.7=10-1.6*5-0.18=2-0.18=1.82

15.52-1.6*2 .05=15.52-3.28=12.24.

简便计算15.52-1.6*5+9.7=15.52-8+9.7=7.52+9.7=17.22

15.52-1.6*2.05=15.52-1.6*2-1.6x0.05=15.52-3.2-0.08=12.32-0.08=12.24

解:15.52-1.6x5-5.7 =15.52-8-5.7 =15.52-(8+5.7) =15.52-13.7 =1.82 祝你学习进步!
