Đúng ghi Đ, sai ghi S? 5/9 = 45/72
20/23
Đúng ghi Đ, sai ghi S?
\(\frac{5}{9} = \frac{{45}}{{72}}\) | \(\frac{{14}}{{33}} = \frac{{42}}{{101}}\) | \(\frac{{100}}{{15}} = \frac{{20}}{3}\) |
\(\frac{{200}}{{50}} = 4\) | \(\frac{{21}}{{54}} = \frac{7}{{18}}\) | \(\frac{{102}}{{46}} = \frac{{17}}{8}\) |
Giải thích
\(\frac{5}{9} = \frac{{45}}{{72}}\) S | \(\frac{{14}}{{33}} = \frac{{42}}{{101}}\) S | \(\frac{{100}}{{15}} = \frac{{20}}{3}\) Đ |
\(\frac{{200}}{{50}} = 4\) Đ | \(\frac{{21}}{{54}} = \frac{7}{{18}}\) Đ | \(\frac{{102}}{{46}} = \frac{{17}}{8}\) S |
