《2025年亮点给力大试卷六年级数学上册苏教版江苏专版》

1. 直接写出得数。(4分)
$\frac {4}{7}÷8=$$\frac{1}{14}$ $\frac {8}{9}÷\frac {9}{8}=$$\frac{64}{81}$ $\frac {7}{16}+\frac {1}{16}=$$\frac{1}{2}$
$\frac {5}{6}÷\frac {5}{12}=$2 $\frac {8}{9}×30=$$\frac{80}{3}$ $\frac {5}{12}×\frac {2}{3}=$$\frac{5}{18}$
$2÷3×\frac {2}{3}=$$\frac{4}{9}$ $\frac {1}{2}×\frac {1}{5}÷\frac {1}{2}×\frac {1}{5}=$$\frac{1}{25}$

答案： $\frac{1}{14}$ $\frac{64}{81}$ $\frac{1}{2}$ 2 $\frac{80}{3}$ $\frac{5}{18}$ $\frac{4}{9}$ $\frac{1}{25}$

2. 计算下面各题。(12分)
$\frac {6}{7}×\frac {35}{12}×\frac {6}{5}$ $\frac {13}{16}÷\frac {3}{4}÷\frac {26}{3}$ $\frac {11}{35}×15÷\frac {22}{7}$
$\frac {5}{7}÷\frac {9}{14}×\frac {4}{5}$ $\frac {3}{5}÷6÷\frac {1}{15}$ $51÷\frac {17}{5}×\frac {10}{9}$

答案： 3 $\frac{1}{8}$ $\frac{3}{2}$ $\frac{8}{9}$ $\frac{3}{2}$ $\frac{50}{3}$

3. 解方程。(6分)
$x÷\frac {6}{25}= \frac {5}{12}$ $\frac {25}{49}x= \frac {30}{7}$ $\frac {3}{10}x÷\frac {7}{16}= \frac {12}{35}$

答案： $x=\frac{1}{10}$ $x=\frac{42}{5}$ $x=\frac{1}{2}$

4. 先化简下面各比,再求比值。(6分)
$25:\frac {5}{6}$ $2.1:0.7$ $\frac {3}{4}$千克:500克

答案： $30:1$ 30 $3:1$ 3 $3:2$ $\frac{3}{2}$
