hoi mot dang ,tra loi 1 leo,zoi oi
\(\frac{-5}{8}.\frac{5}{12}+\frac{-5}{8}.\frac{7}{12}+2\frac{1}{8}\)
\(19\frac{5}{8}:\frac{7}{12}-13\frac{1}{4}:\frac{7}{12}x\frac{4}{5}\)
Tìm x:
\(\frac{1}{3}x-1,2x-\frac{2}{23}.\left(\frac{-11}{12}+\frac{5}{6}-\frac{7}{8}\right)-\frac{1}{8}=-11\frac{2}{3}+12\frac{7}{8}\)
Mina-san giúp đi mè !Đúng thì Chư tiks cho! ^^
Tính:
a)\(\frac{5}{-7}+\frac{-7}{-8}-\frac{2}{7}+\frac{1}{8}-\frac{-1}{12}+\frac{-13}{12}\)
b)\(\frac{-3}{8}-\frac{12}{11}+\frac{3}{-5}+\frac{11}{8}-\frac{-1}{11}-\frac{2}{5}\)
Mình đang cần gấp . Bạn nào giúp thì mình cảm ơn nhiều !!!!!
a,\(\frac{8}{8}x-\frac{2}{3}=\frac{1}{3}x+1\frac{1}{3}\)
b,\(3\frac{1}{4}.x-1\frac{1}{6}.x-1\frac{2}{3}=\frac{5}{12}\)
tìm x :\(\frac{\left(28\frac{3}{7}-27\frac{5}{9}\right).\left(2^{26}+5.4^{12}\right)}{8^{8.}\left(x-4\right)}\)
Tìm x
\(X:\frac{8}{5}+\frac{-7}{3}=\frac{5}{12}\)
1) \(\frac{24}{-12}=\frac{x}{5}=\frac{-y}{3}\)Tìm x và y
2) \(\frac{1}{3}+\frac{-2}{5}+\frac{1}{6}+\frac{-5}{25}\le\frac{x}{10}< \frac{-3}{4}+\frac{4}{14}+\frac{-2}{8}+\frac{-3}{5}+\frac{5}{7}\)Tìm x
3) \(\frac{8.x+18}{2.x+6}\)Tìm x
Tìm x:
\(-\frac{5}{17}+\frac{3}{17}\le\frac{x}{17}\le\frac{13}{17}+-\frac{11}{17}\)
\(\frac{5}{6}+-\frac{7}{8}\le\frac{x}{24}\le-\frac{5}{12}+\frac{5}{8}\)
\(\frac{8}{17}+\frac{5}{17}< \frac{x}{17}< \frac{6}{17}+\frac{9}{17}\)
\(-\frac{6}{7}+\frac{3}{35}< \frac{x}{35}\le-\frac{2}{5}+\frac{3}{7}\)
ai nhanh và đúng mk tick
