44x(5-6/11)+45x(5-4/9)
=44*(55/11-6/11)+45*(45/9-4/9)
=44*49/11+45*41/9
=4*49+5*41=401追问44x11分之5-6+45x9分之5-4是没有括号的哦追答44x5-6/11+45x5-4/9=44*5+45*5-6/11-4/9
=89*5-54/99-44/99=89*5-98/99=(445*99-98)/99
= 444.010101010101
44x11分之5-6+45x9分之5-4
=4*5-6+5*5-4=45-10=35
=44*(55/11-6/11)+45*(45/9-4/9)
=44*49/11+45*41/9
=4*49+5*41=401追问44x11分之5-6+45x9分之5-4是没有括号的哦追答44x5-6/11+45x5-4/9=44*5+45*5-6/11-4/9
=89*5-54/99-44/99=89*5-98/99=(445*99-98)/99
= 444.010101010101
44x11分之5-6+45x9分之5-4
=4*5-6+5*5-4=45-10=35

44*(5-6/11)
=220-24
=196
45*(5-4/9)
=225-20
=205追问44x11分之5-6+45x9分之5-4是没有括号的哦追答你的意思是:
44*5/11-6+45*5/9-4
=20-6+25-4
=35
这样吗?追问是44x5-6(分子)/11(分母)+45x5-4(分子)/9(分母)追答44*5-6/11+45*5-4/9
=220-6/11+225-4/9
=445-98/99
=444.010101....
