Worked solution

1. 将小数化为最简分数

0.375=3751000=380.375 = \dfrac{375}{1000} = \dfrac{3}{8}

2. 利用分数与除法的关系以及分数的基本性质求出其他等式中的未知数

根据分数与除法的关系,38=3÷8\dfrac{3}{8} = 3 \div 8。
根据商不变的性质或分数的基本性质:

  • 分子和分母同时乘 2 得:38=616=6÷16\dfrac{3}{8} = \dfrac{6}{16} = 6 \div 16,因此第一个除号前的空格填 66;
  • 分子和分母同时乘 8 得:38=2464=24÷64\dfrac{3}{8} = \dfrac{24}{64} = 24 \div 64,因此第二个除数处的空格填 6464;
  • 分子和分母同时乘 10 得:38=3080\dfrac{3}{8} = \dfrac{30}{80},因此分母处的空格填 8080。

3. 将小数或分数化为百分数

0.375=37.5%0.375 = 37.5\%

Answer

3; 8; 6; 64; 80; 37.5
