423.4%8.54%1.46简便计算

23.79-8.54+ 1.46=15.25+1.46=16.71

23.4-8.54-1.46+7.6=(23.4+7.6)-(8.54+1.46)=31-10=21

8.54-4.32-3.68+1.46=(8.54+1.46)-(4.32+3.68)=10-8=2

你好!32.54-(8.54-6.88)=32.54-8.54+6.88=24+6.88=30.88打字不易,采纳哦!

(1)23.4-8.54-1.46=23.4-(8.54+1.46)=23.4-10=13.4;(2)428*78+572*78=(428+572)*78=1000*78=78000;(3)216+64*42÷28=216+2688÷28=216+96=312;(4)125*89*8=125*8*89=1000*89=89000;(5)8.29+3.7+0.71+6.3=(8.29+0.71)+(3.7+6.3)=9+10=19;(6)15*27-3000÷25=405-120=285.

1.46*0.5+8.54/2=1.46*0.5+8.54*0.5=(1.46+8.42)*0.5=10*0.5=5

32.54-(8.54-6.88)=32.54-8.54+6.88=24+6.88=30.88 不懂可追问,有帮助请采纳,谢谢!

23.4-8.54+3.6-3.46 =(23.4+3.6)-(8.54+3.46) =27-12 =15

你好! 8.54*6.6 =(8+0.50+0.04)*6.6 =8*6.6+0.50*6.6+0.04*6.6 =52.8+3.3+0.264 =56.364 仅代表个人观点,不喜勿喷,谢谢.

8.54-5.96=8.54-(6-0.04)=8.54-6+0.04=2.54+0.04=2.58
