Question

tính giá trị biểu thức 5/8:4/5+3/8:4/5

Answer 1

\(\frac{5}{8}:\frac{4}{5}+\frac{3}{8}:\frac{4}{5}\) =  \(\left(\frac{5}{8}+\frac{3}{8}\right):\frac{4}{5}=1:\frac{4}{5}=\frac{5}{4}\)

Answer 2

\(\frac{5}{8}:\frac{4}{5}+\frac{3}{8}:\frac{4}{5}\)

\(=\left(\frac{5}{8}+\frac{3}{8}\right):\frac{4}{5}\)

\(=1:\frac{4}{5}\)

\(=\frac{5}{4}\)
