(2/3)+(4/5-2/3)×(5/3)
=(2/3)+(4/3)-(2/3)×(5/3)
=(2/3)+(2/3)×2-(2/3)×(5/3)
=(2/3)×[1+2-(5/3)]
=(2/3)×(4/3)
=(8/9)

希望我的答案令您满意,并能采纳我的回答为最佳答案,谢谢!

(2/3)+(4/5-2/3)×(5/3)
=(2/3)+(4/3)-(2/3)×(5/3)
=(2/3)+(2/3)×2-(2/3)×(5/3)
=(2/3)×[1+2-(5/3)]
=(2/3)×(4/3)
=(8/9)
2/3+(4/5-2/3)x5/3
=2/3+4/5*5/3-2/3*5/3
=4/3-2/3*(5/3-1)
=4/3-2/3*2/3
=4/3-4/3
=0

解:原式 =2/3+4/5*5/3-2/3*5/3
=4/3-2/3*(5/3-1)
=4/3-2/3*2/3
=4/3-4/3
=0
不知道你明不明白 不明白可以给我留言:)

网友(4):

2/3+(4/5-2/3)x5/3
=(2/3)+(4/5)*(5/3)-(2/3)*(5/3)
=(2/3)+(4/3)-(2/3)*(5/3)
=(2/3)+2*(2/3)-(2/3)*(5/3)
=(2/3)*(1+2)-(10/9)
=(2/3)*3-(10/9)
=2-(10/9)
=8/9

网友(5):

2/3+(4/5-2/3)x5/3
=2/3+4/5*5/3-2/3*5/3
=4/3-2/3*(5/3-1)
=4/3-2/3*2/3
=4/3-4/3
=0
