《2025年小学学霸天天计算六年级上册苏教版》

1. $1.6×5\% = $0.08 $7×8\% = $0.56 $70\% -10\% = $0.6
$8.5÷17\% = $50 $3.5×30\% = $1.05 $32\% ÷16= $0.02
$4.1+35\% = $4.45 $2.25×40\% = $0.9 $6.75÷50\% = $13.5
$\frac {10}{9}×18\% = $0.2 $\frac {3}{10}+70\% = $1 $\frac {7}{12}×30\% = $$\frac{7}{40}$

答案： 1. 0.08 0.56 0.6
50 1.05 0.02
4.45 0.9 13.5
0.2 1 $\frac{7}{40}$

2. $0.72= \frac {18}{25}= 36:50= 360÷500= 72\%$
$150\% = 1.5$(填小数)$=\frac {30}{20}= 12:8= 0.6÷0.4$
$\frac {11}{20}= 0.55$(填小数)$=55\% = 33:60= 121÷220$

答案： 2. 18 50 360 72
1.5 20 8 0.6
0.55 55 33 220

3. 计算下面各题,能简算的要简算。
$20\% ×1.7×50$ $70\% ×(\frac {4}{7}÷\frac {1}{4})$ $\frac {5}{13}×(\frac {7}{8}+\frac {3}{4})×80\%$
$\frac {1}{6}÷\frac {13}{24}×50\%$ $(\frac {1}{24}+\frac {1}{32})÷12.5\%$ $\frac {11}{12}×27\% +0.27×\frac {1}{12}$

答案： （1）计算$20\%×1.7×50$
解：
$\begin{aligned}&20\%×1.7×50\\=&0.2×50×1.7\\=&10×1.7\\=&17\end{aligned}$
（2）计算$70\%×(\frac{4}{7}÷\frac{1}{4})$
解：
$\begin{aligned}&70\%×(\frac{4}{7}÷\frac{1}{4})\\=&0.7×(\frac{4}{7}×4)\\=&0.7×\frac{16}{7}\\=&1.6\end{aligned}$
（3）计算$\frac{5}{13}×(\frac{7}{8}+\frac{3}{4})×80\%$
解：
$\begin{aligned}&\frac{5}{13}×(\frac{7}{8}+\frac{3}{4})×80\%\\=&\frac{5}{13}×(\frac{7}{8}+\frac{6}{8})×\frac{4}{5}\\=&\frac{5}{13}×\frac{13}{8}×\frac{4}{5}\\=&\frac{5}{8}×\frac{4}{5}\\=&\frac{1}{2}\end{aligned}$
（4）计算$\frac{1}{6}÷\frac{13}{24}×50\%$
解：
$\begin{aligned}&\frac{1}{6}÷\frac{13}{24}×50\%\\=&\frac{1}{6}×\frac{24}{13}×\frac{1}{2}\\=&\frac{4}{13}×\frac{1}{2}\\=&\frac{2}{13}\end{aligned}$
（5）计算$(\frac{1}{24}+\frac{1}{32})÷12.5\%$
解：
$\begin{aligned}&(\frac{1}{24}+\frac{1}{32})÷12.5\%\\=&(\frac{4}{96}+\frac{3}{96})÷\frac{1}{8}\\=&\frac{7}{96}×8\\=&\frac{7}{12}\end{aligned}$
（6）计算$\frac{11}{12}×27\%+0.27×\frac{1}{12}$
解：
$\begin{aligned}&\frac{11}{12}×27\%+0.27×\frac{1}{12}\\=&0.27×(\frac{11}{12}+\frac{1}{12})\\=&0.27×1\\=&0.27\end{aligned}$
综上，答案依次为$17$；$1.6$；$\frac{1}{2}$；$\frac{2}{13}$；$\frac{7}{12}$；$0.27$。
