\(x-0,27=\frac{\frac{73}{77}+\frac{73}{165}+\frac{73}{285}}{25.\left(\frac{5}{84}+\frac{3}{180}+\frac{4}{285}\right)}\)

\(x-\frac{27}{100}=\frac{73.\left(\frac{1}{77}+\frac{1}{165}+\frac{1}{285}\right)}{25.4.\left(\frac{5}{4.84}+\frac{3}{4.180}+\frac{4}{4.285}\right)}\)

\(x=\frac{73}{100}+\frac{27}{100}\)

\(x=1\)

Vậy x=1

\(x=1\)nha bạn

x-0,27=(73/77+73/165+73/185):[25.12/133)

x-0,27=(73/77+73/165+73/185):[25/1.12/133)

x-0,27=(73/77+73/165+73/185):300/133

x-0,27=1387/777:300/133

x-0,27=0,791381381

x=0,791381381-0,27

x=0,521381381

                                                                                Bài làm 

x-0.27=\(\frac{73}{100}\)

x= \(\frac{73}{100}\)+\(\frac{27}{100}\)

x=\(\frac{100}{100}\)=1

      Vậy x = 1 

\(x-0,27=\frac{\frac{73}{77}+\frac{73}{165}+\frac{73}{285}}{28.\left(\frac{5}{84}+\frac{3}{285}+\frac{4}{285}\right)}\)

\(x-\frac{27}{100}=\frac{73.\left(\frac{1}{77}+\frac{1}{165}+\frac{1}{285}\right)}{25.4.\left(\frac{5}{4.84}+\frac{3}{4.180}+\frac{4}{4.285}\right)}\)

\(x-\frac{27}{100}=\frac{73,\left(\frac{2}{105}+\frac{1}{285}\right)}{100.\left(\frac{5}{366}+\frac{3}{240}+\frac{4}{285}\right)}\)

\(x-\frac{27}{100}=\frac{73.\left(\frac{2}{105}+\frac{1}{285}\right)}{100.\left(\frac{2}{105}+\frac{1}{285}\right)}\)

\(x-\frac{27}{100}=\frac{73}{100}\)

\(x=\frac{27}{100}+\frac{73}{100}\)

\(\Rightarrow x=1\)

bạn nguyen thi thuy linh ơi bạn làm sai đề của mk rồi

câu trả lời là:

 798,5873

  Đáp số: ........

  k nha

Tìm x :

x - 0,27 = \(\frac{73}{100}\)

x           = \(\frac{73}{100}+0,27\)

x           = 1

Cậu P khó quá mik chưa nghĩ ra cách tính nhanh nhất !

Cậu tự giải nhé !

Hok tốt

\(x-0,27=\frac{\frac{73}{77}+\frac{73}{165}+\frac{73}{285}}{25\times\left(\frac{5}{84}+\frac{3}{180}+\frac{4}{285}\right)}.\)

\(x-0,27=\frac{\frac{146}{105}+\frac{73}{285}}{25\times\left(\frac{8}{105}+\frac{4}{285}\right)}\)

\(x-0,27=\frac{\frac{219}{133}}{25\times\frac{12}{133}}\)

\(x-0,27=\frac{\frac{219}{133}}{\frac{300}{133}}\)

\(x-0,27=0,73\)

\(x=0,73+0,27\)

\(x=1\)
