\(\frac{323}{34}+\frac{34}{345}\times84=17\frac{179}{230}\)
\(\frac{323}{34}+\frac{34}{345}\times84=17\frac{179}{230}\)
\(\frac{34}{245}\) x \(\frac{323}{23}\)+ 467 = bao nhieu
A) \(\frac{252}{X}\) = \(\frac{84}{97}\) B) \(\frac{x}{17}\) + \(\frac{19}{34}\) = \(\frac{1}{2}\)
Rút Gọn:
a.\(\frac{36}{25}.\frac{85}{84}.\frac{20}{34}\)
b.\(\frac{7}{11}.\frac{-39}{190}.\frac{33}{13}.\frac{76}{21}\)
c.\(-\frac{11}{12}.\frac{4}{35}.\frac{84}{-25}.\frac{5}{6}\)

1)\(\left(\frac{1}{2}-\frac{1}{3}-\frac{1}{6}\right).\left(\frac{3}{8}+\frac{34}{88}-\frac{345}{888}\right)\)
2)\(\frac{8}{3}.\frac{2}{5}.\frac{3}{8}.10.\frac{19}{92}\)
Tìm x, biết:
Tính bằng cách hợp lý:
Tính B=\(\frac{48+\frac{34}{31}-\frac{34}{33}+\frac{34}{35}}{72+\frac{51}{31}-\frac{51}{33}+\frac{51}{35}}:\frac{-242423}{363636}\)
Tìm x,y Z biết:
a) \(\frac{x}{7}\)= \(\frac{9}{y}\)và x > y
b) \(\frac{-2}{x}\)= \(\frac{y}{5}\)và x < 0 < y
c) \(\frac{x-4}{y-3}\)= \(\frac{4}{3}\)và x - y = 5
\(\frac{34}{9}\). x : (9 - \(\frac{-13}{9}\)) -\(\frac{1}{4}\)=34
Mk cần gấp
\(\left(0,25+\frac{-11}{9}\right)\cdot\frac{5}{34}\left(\frac{-2}{9}+7\frac{1}{4}\right)\cdot\frac{5}{34}\)
