\(5\frac{5}{27}+\frac{7}{23}+0,5-\frac{5}{27}+\frac{16}{23}\)
\(5\frac{5}{27}+\frac{7}{23}+0,5-\frac{5}{27}+\frac{16}{23}\)
\(=\left(5\frac{5}{27}-\frac{5}{27}\right)+\left(\frac{7}{23}+\frac{16}{23}\right)+0,5\)
\(=5+\frac{23}{23}+0,5=5,5+1=6,5\)

Tính giá trị biểu thức:
7) G= \(\frac{1}{25}-\frac{4}{27}+\left(\frac{-23}{27}+\frac{-1}{25}-\frac{5}{43}\right)+\frac{5}{43}-\frac{4}{7}\)
\(G=\frac{1}{25}-\frac{4}{27}+\left(\frac{-23}{27}+\frac{-1}{25}-\frac{5}{43}\right)+\frac{5}{43}-\frac{4}{7}\)
\(=\frac{1}{25}-\frac{4}{27}+\frac{-23}{27}+\frac{-1}{25}-\frac{5}{43}+\frac{5}{43}-\frac{4}{7}\)
\(=\left(\frac{1}{25}+\frac{-1}{25}\right)+\left(\frac{-4}{27}+\frac{-23}{27}\right)+\left(\frac{-5}{43}+\frac{5}{43}\right)-\frac{4}{7}\)
\(=0+\left(-1\right)+0-\frac{4}{7}\)
