Question

\(\frac{0.\left(3\right)+0.\left(384615\right)+\frac{3}{13}x}{0.0\left(3\right)+13}\)

 

Giups mik nha

Answer 1

Đề bài là gì vậy bạn ??? Tính hay tìm x ?

\(\frac{0,\left(3\right)+0,\left(384615\right)+\frac{3}{13}x}{0,0\left(3\right)+13}\)

\(=\frac{\frac{1}{3}+\frac{5}{13}+\frac{3}{13}x}{\frac{1}{30}+13}=\frac{\frac{1}{3}+\frac{5+3x}{13}}{\frac{391}{30}}=\frac{\frac{13+3\left(5+3x\right)}{39}}{\frac{391}{30}}\)

\(=\frac{\frac{13+15+9x}{39}}{\frac{391}{90}}=\frac{\frac{28+9x}{39}}{\frac{391}{90}}=\frac{28+9x}{39}\cdot\frac{90}{391}\)

P/S : Sai đề trầm trọng

Answer 2

Tìm x nha

Answer 3

P/S : Tìm x vậy kết quả nó bao nhiêu mới tìm được chớ ?

Đề còn thiếu không vậy?

Answer 4

\(\frac{50}{85}\)

Answer 5

\(\frac{0,\left(3\right)+0,\left(384615\right)+\frac{3}{13}x}{0,0\left(3\right)+13}=\frac{50}{85}\)

=> \(\frac{\frac{1}{3}+\frac{5}{13}+\frac{3}{13}x}{\frac{1}{30}+13}=\frac{50}{85}\)

=> \(\frac{1}{3}+\frac{5}{13}+\frac{3}{13}x=\frac{50}{85}\cdot\left(\frac{1}{30}+13\right)\)

=> \(\frac{1}{3}+\frac{5}{13}+\frac{3}{13}x=\frac{50}{85}\cdot\frac{391}{30}=\frac{23}{3}\)

=> \(\frac{28}{39}+\frac{3}{13}x=\frac{23}{3}\)

=> \(\frac{3}{13}x=\frac{23}{3}-\frac{28}{39}=\frac{271}{39}\)

=> \(x=\frac{271}{39}:\frac{3}{13}=\frac{271}{39}\cdot\frac{13}{3}=\frac{271}{9}\)
