Question

1/3x+55=3/4x怎么解小学方法？

Answer 1

1/3x+55=3/4x
4x+55×12=9x 两边同时乘以12
9x-4x=55×12 合并同类项
x=55×12÷5 系数化为1
x=132

Answer 2

1/3x+55＝3/4x
3/4x-1/3x=55
（9/12-4/12）x=55---运用到通分
5/12x=55
x＝55÷5/12
x＝55×12/5---一个数除以分数等于乘上它的倒数
x＝132

Answer 3

1/3x+55=3/4x怎么解小学方法？
55=3/4x-1/3x
55=9/12x-4/12x
5/12x=55
x=55×12/5
x=132
望采纳 谢谢~~

Answer 4

1/3x+55=3/4x
解：3/4x-1/3x=55
9/12x-4/12x=55
5/12x=55
x=55÷(5/12)
x=132

Answer 5

先将1/3×和3/4×化为同分母，得到4/12×和9/12×，然后两边同时减去4/12×，即55＝5/12×，算出×＝132
