Trong các phân số dưới đây, phân số lớn nhất là:

Đáp án đúng là: B

\(\frac{5}{8}\,\, = \,\,\frac{{5\,\, \times \,\,3}}{{8\,\, \times \,\,3}}\,\, = \,\,\frac{{15}}{{24}}\)

\(\frac{5}{6}\,\, = \,\,\frac{{5\,\, \times \,\,4}}{{6\,\, \times \,\,4}}\,\, = \,\,\frac{{20}}{{24}}\)

\(\frac{3}{4}\,\, = \,\,\frac{{3\,\, \times \,\,6}}{{4\,\, \times \,\,6}}\,\, = \,\,\frac{{18}}{{24}}\)

\(\frac{2}{3}\,\, = \,\,\frac{{2\,\, \times \,\,8}}{{3\,\, \times \,\,8}}\,\, = \,\,\frac{{16}}{{24}}\)

So sánh: \(\frac{{15}}{{24}}\,\, < \,\,\frac{{16}}{{24}}\,\, < \,\,\frac{{18}}{{24}}\,\, < \,\,\frac{{20}}{{24}}\)
