将下列分数写成带分数,并按升序排列
$\frac{11}{8} , \frac{17}{12}, \frac{5}{3}, \frac{8}{6} $
已知
给定的分数是:$\frac{11}{8} , \frac{17}{12}, \frac{5}{3}, \frac{8}{6} $
要求
我们将给定的分数写成带分数,并按升序排列。
解答
$\frac{11}{8} = \frac{11\times 3}{8\times 3} = \frac{33}{24} =\frac{ (24+9)}{24} = 1\frac {9}{24}$
$\frac{17}{12} = \frac{17\times 2}{12\times 2} = \frac{34}{24} =\frac{ (24+10)}{24} = 1\frac {10}{24}$
$\frac{5}{3} = \frac{5\times 8}{3\times 8} = \frac{40}{24} =\frac{ (24+16)}{24} = 1\frac {16}{24}$
$\frac{8}{6} = \frac{8\times 4}{6\times 4} = \frac{32}{24} =\frac{ (24+8)}{24} = 1\frac {8}{24}$
比较这些分数,
$1\frac {8}{24}< 1\frac {9}{24} <1\frac {10}{24} < 1\frac {16}{24}$.
因此,
给定数字的升序排列是 $\frac{8}{6},\frac{11}{8}, \frac{17}{12}, \frac{5}{3}$.
