Question

thực hiện phép tính:\(\frac{4+\frac{4}{17}+\frac{4}{19}+\frac{4}{2003}}{5+\frac{5}{17}+\frac{5}{19}+\frac{5}{2003}}\)

*bạn nào làm trước mk tick cho

 

 

Answer 1

\(\frac{4+\frac{4}{17}+\frac{4}{19}+\frac{4}{2003}}{5+\frac{5}{17}+\frac{5}{19}+\frac{5}{2003}}\)

= \(\frac{4.\left(1+\frac{1}{17}+\frac{1}{19}+\frac{1}{2003}\right)}{5.\left(1+\frac{1}{17}+\frac{1}{19}+\frac{1}{2003}\right)}\)

= \(\frac{4}{5}\)

Answer 2

\(\frac{4+\frac{4}{17}+\frac{4}{19}+\frac{4}{2003}}{5+\frac{5}{17}+\frac{5}{19}+\frac{5}{2003}}=\frac{4\left(1+\frac{1}{17}+\frac{1}{19}+\frac{1}{2003}\right)}{5\left(1+\frac{1}{17}+\frac{1}{19}+\frac{1}{2003}\right)}=\frac{4}{5}\)

Answer 3

\(\frac{4+\frac{4}{17}+\frac{4}{19}+\frac{4}{2003}}{5+\frac{5}{17}+\frac{5}{19}+\frac{5}{2003}}\)

\(=\frac{4.(\frac{1}{17}+\frac{1}{19}+\frac{1}{2003})}{5.(\frac{1}{17}+\frac{1}{19}+\frac{1}{2003})}\)

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