bạn nguyen thi thuy linh ơi bạn làm sai đề của mk rồi
Tìm x , biết :
\(x-0,27=\left(\frac{73}{77}+\frac{73}{165}+\frac{73}{285}\right):\left[25.\left(\frac{5}{84}+\frac{3}{180}+\frac{4}{285}\right)\right]\)
giải nhanh giúp mình nhé ! mình tick cho
\(x=1\)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=\(\frac{\frac{73}{77}+\frac{73}{165}+\frac{73}{285}}{25.\left(\frac{5}{84}+\frac{3}{180}+\frac{4}{285}\right)}\)

\(x-\frac{27}{100}=\frac{73.\left(\frac{2}{105}+\frac{1}{285}\right)}{100.\left(\frac{2}{105}+\frac{1}{285}\right)}\)
\(x-\frac{27}{100}=\frac{73}{100}\)
\(x=\frac{73}{100}+\frac{27}{100}\)
\(x=1\)
Vậy x=1
Tính :
x-0,27=\(\frac{\frac{73}{77}+\frac{73}{165}+\frac{73}{285}}{\subset\frac{5}{84}+\frac{3}{180}+\frac{4}{285}\supset x25}\)
