giúp e với ạ. 10h e phải nộp r
😟😟😢😢
\(=\left(\dfrac{4}{23}+\dfrac{19}{23}\right)+\left(4+\dfrac{5}{6}+0.5+1.5\right)-\dfrac{5}{16}\)
\(=\dfrac{11}{16}+5+\dfrac{5}{6}\)
\(=\dfrac{11}{16}+\dfrac{36}{5}\)
\(=\dfrac{631}{80}\)

1. 5/21+0,5-19/23+16/21-4/23
2. 27/23+5/21-4/23+6/21+1/2
giải giúp mình nhé mấy bạn
1.\(\left(\frac{-6}{5}+\frac{6}{16}-\frac{6}{23}\right):\left(\frac{9}{5}-\frac{9}{19}+\frac{9}{23}\right)\)
2.\(\frac{\frac{3}{7}-\frac{3}{-11}+\frac{3}{13}}{\frac{5}{7}-\frac{5}{11}+\frac{5}{13}}+\frac{0,5-\frac{1}{3}+\frac{1}{4}}{\frac{-3}{2}+1-\frac{3}{4}}\)
a. \(\frac{5}{21}+0,5-\frac{19}{23}+\frac{16}{21}-\frac{4}{23}\)
giúp mk vs ai nhanh nhất mk tk cho
1/4/23-5/21-4/23+1,5+1/16/21
1/4/23+5/21-4/23+0,5+16/21
A=1/4/23-5/21-4/23+/1,5+1/16/21
B=1/5√100-√9/16
|2005-x|*2004=2005
1 va 4/23 - 5/-21 - 4/23 - 0,5 + 2 va 16/21
\(4\frac{5}{16}+\frac{4}{23}+0.5-\frac{5}{16}+\frac{19}{23}\)
\(5\dfrac{5}{27}+\dfrac{7}{23}-0,5.\dfrac{5}{27}+\dfrac{16}{23}=\)
\(45\dfrac{1}{6}:\left(\dfrac{-4}{5}\right)-35\dfrac{1}{6}:\left(\dfrac{-4}{5}\right)=\)
\(25.\left(\dfrac{-1}{5}\right)^3+\dfrac{1}{5}-2.\left(\dfrac{-1}{2}\right)^2-\dfrac{1}{2}=\)
\(\left(3,1-2,5\right)-\left(-2,5-3,1\right)=\)
\(\dfrac{3}{8}.\dfrac{7}{5}-\dfrac{7}{5}.\dfrac{1}{8}+\dfrac{13}{20}=\)
