第二个好像是老师出错题了,应该和第一个一样。

求2数学题,简算!32×2/5+64÷536×2/5+64÷5第二个好像是老师出错题了,应该和第一个一样。
32×2/5+64÷5
=32x(2/5+2/5)
=32x4/5
=128/5
36×2/5+64÷5
=36×2/5+32x2/5
=2/5x(36+32)
=2/5x68
=136/5

32×2/5+64÷5
=64÷5+64÷5
=128÷5
=25又5分之3
36×2/5+64÷5
=72/5+64/5
=136/5
=27.2

32×2/5+64÷5
=64/5+64/5
=64*2/5
=128/5
36×2/5+64÷5
=72/5+64/5
=(64+72)/5
=136/5
祝学习进步

25.6 27.2

32×2/5+64÷5=64÷5*2=64*2÷5=25.6

32×2/5+64÷5
=32x(2/5+2/5)
=32x4/5
=128/5

36×2/5+64÷5
=36×2/5+32x2/5
=2/5x(36+32)
=2/5x68
=136/5
不懂的追问哈,最近分有点紧,给我吧

32×2/5+64÷5
=64/5+64/5
=128/5
=25.6(即25又3/5)
36×2/5+64÷5
=72/5+64/5
=136/5
=27.2(即27又1/5)

32×2/5+64÷5
=64/5+64/5
=64/5×2
=128/5
36×2/5+64÷5
=4(18/5+16/5)
=4*34/5
=136/5
