1. 根据涂色部分填写分数,并比较大小。
$\frac{(\ \ \ )}{(\ \ \ )}\bigcirc\frac{(\ \ \ )}{(\ \ \ )}$ $\frac{(\ \ \ )}{(\ \ \ )}\bigcirc\frac{(\ \ \ )}{(\ \ \ )}$
$\frac{(\ \ \ )}{(\ \ \ )}\bigcirc\frac{(\ \ \ )}{(\ \ \ )}$ $\frac{(\ \ \ )}{(\ \ \ )}\bigcirc\frac{(\ \ \ )}{(\ \ \ )}$
$\frac{(\ \ \ )}{(\ \ \ )}\bigcirc\frac{(\ \ \ )}{(\ \ \ )}$ $\frac{(\ \ \ )}{(\ \ \ )}\bigcirc\frac{(\ \ \ )}{(\ \ \ )}$
$\frac{(\ \ \ )}{(\ \ \ )}\bigcirc\frac{(\ \ \ )}{(\ \ \ )}$ $\frac{(\ \ \ )}{(\ \ \ )}\bigcirc\frac{(\ \ \ )}{(\ \ \ )}$
答案
2. 涂一涂,比一比。
$\frac{3}{5}\bigcirc\frac{4}{5}$ $\frac{1}{4}\bigcirc\frac{1}{3}$
$\frac{3}{5}\bigcirc\frac{4}{5}$ $\frac{1}{4}\bigcirc\frac{1}{3}$
答案
3. 根据涂色部分写出分数,并按从大到小的顺序排一排。
$\frac{(\ \ \ )}{(\ \ \ )}>\frac{(\ \ \ )}{(\ \ \ )}>\frac{(\ \ \ )}{(\ \ \ )}$
$\frac{(\ \ \ )}{(\ \ \ )}$ $\frac{(\ \ \ )}{(\ \ \ )}$ $\frac{(\ \ \ )}{(\ \ \ )}$
$\frac{(\ \ \ )}{(\ \ \ )}>\frac{(\ \ \ )}{(\ \ \ )}>\frac{(\ \ \ )}{(\ \ \ )}$
$\frac{(\ \ \ )}{(\ \ \ )}$ $\frac{(\ \ \ )}{(\ \ \ )}$ $\frac{(\ \ \ )}{(\ \ \ )}$
