\(x-\frac{x}{3}=\frac{3}{57}:\frac{12}{19}\)
\(x-\frac{x}{3}=\frac{3}{57}\times\frac{19}{12}\)
\(x-\frac{x}{3}=\frac{1}{12}\)
\(\Rightarrow12x-4x=1\)
\(\Rightarrow8x=1\)
\(\Rightarrow x=\frac{1}{8}\)
Tính giá trị biểu thức:
A=\(1\frac{6}{41}\left[\frac{12+\frac{12}{19}+\frac{12}{37}+\frac{12}{53}}{3+\frac{9}{57}+\frac{3}{37}+\frac{3}{53}}:\frac{4+\frac{4}{17}+\frac{4}{19}+\frac{4}{2006}}{5+\frac{5}{17}+\frac{5}{19}+\frac{5}{2006}}\right]\)
Tìm x,y,z biết:
\(\frac{x}{3}=\frac{y}{-9}=\frac{8}{-z}=\frac{-19}{-57}\)
Giải nhanh hộ mình, mình cần gấp!
Thanks
bài 1 Tìm x;y thuộc N* niết
\(\frac{x}{5}-\frac{2}{y}=\frac{2}{15}\)
b) D= \(\frac{2}{3\cdot5}+\frac{3}{5\cdot8}+\frac{11}{8\cdot19}+\frac{13}{19\cdot32}+\frac{25}{32\cdot57}+\frac{30}{57\cdot87}\)
1\(\frac{6}{41}\)x (\(\frac{12+\frac{12}{19}-\frac{12}{37}-\frac{12}{53}}{3+\frac{1}{3}-\frac{3}{37}-\frac{3}{53}}\)x\(\frac{4+\frac{4}{17}+\frac{4}{19}+\frac{4}{2006}}{5+\frac{5}{17}+\frac{5}{19}+\frac{5}{2000}}\))x\(\frac{124242423}{237373735}\)
Bài 1: Tìm x
a. \(x-\frac{5}{12}-\frac{4}{9}=\frac{-13}{18}\)
b. \(2-\left(x+\frac{3}{7}\right)=\frac{9}{-21}\)
c. \(x-\frac{-3}{11}=\frac{6}{22}+\frac{1}{4}\)
d. \(\frac{13}{36}-\frac{5}{18}-x=\frac{-11}{9}\)
e. \(x-\frac{3}{7}:\frac{9}{14}=\frac{-17}{3}\)
f. \(\left(x-\frac{1}{2}\right):\frac{3}{11}=\frac{11}{4}\)
g. \(\left(2x+\frac{3}{8}\right).\frac{7}{4}=-\frac{21}{32}\)
h. \(x-\frac{x}{3}=\frac{3}{57}:\frac{12}{19}\)
Vì dài qua cho nên bài 2 mình để riêng nhé
Bài 1 tìm x
a, x - \(\frac{x}{3}\)= \(\frac{3}{57}\): \(\frac{12}{19}\)
b, (x +\(\frac{1}{4}\)-\(\frac{1}{3}\)) : ( 2 + \(\frac{1}{6}\)- \(\frac{1}{4}\))= \(\frac{7}{46}\)
c, \(\frac{13}{15}\)- ( \(\frac{13}{21}\)+ x) . \(\frac{7}{12}\)= \(\frac{7}{10}\)
Làm chi tiết hộ mình nha
1\(\frac{6}{41}\)(\(\frac{12+\frac{12}{19}-\frac{12}{37}-\frac{12}{53}}{3+\frac{1}{3}-\frac{3}{37}-\frac{3}{53}}\)x\(\frac{4+\frac{4}{17}+\frac{4}{19}+\frac{4}{2006}}{5+\frac{5}{17}+\frac{5}{19}+\frac{5}{2000}}\)) x\(\frac{124242423}{237373735}\)
giúp em mình nhé !!! cảm ơn
A=\(\frac{7}{19}x\frac{8}{11}x\frac{7}{19}:\frac{3}{11}+\frac{12}{19}\)
A=\(\frac{7}{19}x\frac{8}{11}x\frac{7}{19}:\frac{3}{11}+\frac{12}{19}\)
