《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。(8分)
$\frac {1}{4}+\frac {1}{5}=$$\frac{9}{20}$ $12×\frac {5}{18}=$$\frac{10}{3}$ $4÷\frac {2}{11}=$22
$\frac {7}{8}÷\frac {4}{5}=$$\frac{35}{32}$ $\frac {1}{6}-\frac {1}{8}=$$\frac{1}{24}$ $0÷\frac {9}{11}=$0
$\frac {5}{6}×\frac {3}{5}×\frac {2}{7}=$$\frac{1}{7}$ $\frac {4}{5}×\frac {5}{7}÷\frac {5}{7}×\frac {4}{5}=$$\frac{16}{25}$

答案： 1. $\frac{9}{20}$ $\frac{10}{3}$ 22 $\frac{35}{32}$ $\frac{1}{24}$ 0 $\frac{1}{7}$ $\frac{16}{25}$

2. 计算下面各题,能简算的要简算。(18分)
$(\frac {3}{4}+\frac {1}{7}-\frac {1}{2})×28$ $3-\frac {5}{8}÷\frac {7}{16}-\frac {4}{7}$
$\frac {7}{9}×(\frac {1}{3}-\frac {1}{4})÷\frac {7}{18}$ $(\frac {3}{4}-\frac {3}{4}÷\frac {6}{5})×\frac {2}{3}$
$12×(\frac {5}{6}-\frac {4}{5})×5$ $\frac {8}{9}÷[(\frac {2}{5}+\frac {1}{10})×\frac {2}{3}]$

答案： 2. 11 1 $\frac{1}{6}$ $\frac{1}{12}$ 2 $\frac{8}{3}$

3. 解方程。(6分)
$\frac {2}{5}x-\frac {3}{10}= \frac {7}{10}$ $x+\frac {1}{3}x= \frac {8}{15}$ $\frac {1}{2}x÷\frac {2}{3}= \frac {1}{3}$

答案： 3. $x=\frac{5}{2}$ $x=\frac{2}{5}$ $x=\frac{4}{9}$
