《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)
$36×25\% = $9 $\frac {1}{3}÷3 = $$\frac{1}{9}$ $18÷1\% = $1800
$7÷\frac {7}{9} = $9 $\frac {2}{21}×7 = $$\frac{2}{3}$ $\frac {10}{7}÷\frac {5}{21} = $6
$\frac {13}{7}-25\% -75\% = $$\frac{6}{7}$ $(\frac {1}{24}-\frac {1}{32})÷12.5\% = $$\frac{1}{12}$

答案： 9 $\frac{1}{9}$ 1800 9 $\frac{2}{3}$ 6 $\frac{6}{7}$ $\frac{1}{12}$

2. 计算下面各题,能简算的要简算。(12分)
$(\frac {7}{12}-\frac {1}{8})×\frac {8}{7}$ $(\frac {7}{8}-\frac {1}{12}+\frac {1}{6})×24$
$\frac {3}{4}×\frac {2}{9}+75\% ÷\frac {9}{7}+\frac {1}{4}$ $\frac {9}{17}×[1-(\frac {5}{9}-\frac {4}{9})]$

答案： 1. $\frac{11}{21}$ 2. 23 3. 1 4. $\frac{8}{17}$

3. 解方程。(9分)
$\frac {1}{2}x+\frac {3}{5}x= \frac {11}{15}$ $\frac {1}{4}x÷\frac {1}{2}= \frac {3}{4}$ $20\% x + 50.8 = 90.3$

答案： 1. $x=\frac{2}{3}$ 2. $x=\frac{3}{2}$ 3. $x=197.5$
