A. \(\dfrac{{23}}{{99}} = \dfrac{{2323}}{{9999}} = \dfrac{{232323}}{{999999}} >\dfrac{{23232323}}{{99999999}} \)
B. \(\dfrac{{23}}{{99}} > \dfrac{{2323}}{{9999}} > \dfrac{{232323}}{{999999}} >\dfrac{{23232323}}{{99999999}} \)
C. \(\dfrac{{23}}{{99}} = \dfrac{{2323}}{{9999}} > \dfrac{{232323}}{{999999}} >\dfrac{{23232323}}{{99999999}} \)
D. \(\dfrac{{23}}{{99}} = \dfrac{{2323}}{{9999}} = \dfrac{{232323}}{{999999}} =\dfrac{{23232323}}{{99999999}} \)
D
Ta có:
\(\dfrac{{2323}}{{9999}} = \dfrac{{2323:101}}{{9999:101}} = \dfrac{{23}}{{99}}\)
\(\dfrac{{232323}}{{999999}} = \dfrac{{232323:10101}}{{999999:10101}} = \dfrac{{23}}{{99}}\)
\(\dfrac{{23232323}}{{99999999}} = \dfrac{{23232323:1010101}}{{99999999:1010101}} = \dfrac{{23}}{{99}}\)
Vậy \(\dfrac{{23}}{{99}} = \dfrac{{2323}}{{9999}} = \dfrac{{232323}}{{999999}} = \dfrac{{23232323}}{{99999999}}\)
