《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。(10分)
$\frac{3}{5} × 15 =$ $\frac{13}{24} × 4.8 =$ $2 - \frac{3}{7} =$ $1.4 + 20\% =$
$\frac{7}{8} ÷ \frac{7}{10} =$ $5 ÷ \frac{2}{3} =$ $\frac{4}{3} × 75\% =$ $\frac{7}{8} × 4 × \frac{8}{7} =$
$\frac{1}{6} + \frac{5}{6} × \frac{1}{5} =$ $\frac{1}{2} × 99 + 99 × \frac{1}{2} =$

答案： 1.9 2.6 1$\frac{4}{7}$ 1.6 $\frac{5}{4}$ $\frac{15}{2}$ 1 4$\frac{1}{3}$ 99

2. 计算下面各题,能简算的要简算。(18分)
$32 × (\frac{5}{8} - \frac{5}{9}) × 36$ $\frac{1}{4} - \frac{10}{21} × \frac{7}{20} ÷ \frac{5}{6}$
$\frac{7}{12} ÷ [\frac{9}{8} × (\frac{2}{3} - \frac{1}{2})]$ $\frac{7}{8} ÷ [\frac{7}{12} × (\frac{6}{7} + \frac{9}{14})]$
$14 × \frac{51}{43} + 51 × \frac{29}{43}$ $(\frac{2}{3} + \frac{3}{4} - \frac{1}{6}) ÷ \frac{1}{24}$

答案： 2.原式=32×$\frac{5}{8}$×36 - 32×$\frac{5}{9}$×36=720 - 640=80 $\frac{1}{20}$ $\frac{28}{9}$ 1 原式=14×$\frac{51}{43}$+29×$\frac{51}{43}$=(14 + 29)×$\frac{51}{43}$=43×$\frac{51}{43}$=51 原式=$\frac{2}{3}$×24 + $\frac{3}{4}$×24 - $\frac{1}{6}$×24=16 + 18 - 4=30
