《2025年直击考点冲刺100分六年级数学上册苏教版》

1. 直接写出得数。(5分)
$\frac{5}{9} + \frac{1}{6} =$ $18 × \frac{7}{9} =$ $30\% + \frac{1}{2} =$ $\frac{3}{8} ÷ \frac{7}{10} =$
$\frac{3}{4} - 37.5\% =$ $57 ÷ \frac{19}{14} =$ $\frac{1}{3} + \frac{5}{6} =$ $2.2 + 8\% =$
$3 - 199\% =$ $9.53 × 10\% =$

答案： 1.$\frac{13}{18}$　14　0.8　$\frac{15}{28}$　$\frac{3}{8}$　$\frac{7}{42}$　$\frac{7}{6}$　2.28　1.01　0.953

2. 计算下面各题,能简算的要简算。(18分)
$(\frac{5}{6} - 75\%) ÷ \frac{1}{15} - 100\%$ $4 ÷ 80\% + 80\% ÷ 4$
$12.5\% ÷ 75\% × 25\% ÷ 87.5\%$ $\frac{10}{21} ÷ [\frac{5}{6} ÷ (1 - 62.5\%)]$
$\frac{13}{12} - (\frac{1}{12} + 87.5\%) - 12.5\%$ $60\% ÷ [\frac{7}{8} - (40\% - \frac{1}{8})]$

答案： 2.$\frac{1}{4}$　5.2　$\frac{1}{21}$　$\frac{3}{14}$　原式=$\frac{13}{12}$ - $\frac{1}{12}$ - $(87.5\% + 12.5\%)$ = $1 - 1$ = $0$　原式=$\frac{3}{5}$ ÷ $[\frac{7}{8} + \frac{1}{8} - \frac{2}{5}]$ - $\frac{3}{5}$ ÷ $\frac{3}{5}$ = $1$
