答案:
解析:本题考查百分数与最简分数的转换。需要将给出的百分数转换为分母为100的分数,然后化简为最简形式。
答案:
$10\% = \frac{10}{100} = \frac{1}{10}$;
$2\% = \frac{2}{100} = \frac{1}{50}$;
$25\% = \frac{25}{100} = \frac{1}{4}$;
$240\% = \frac{240}{100} = \frac{12}{5}$;
$5\% = \frac{5}{100} = \frac{1}{20}$;
$64\% = \frac{64}{100} = \frac{16}{25}$;
$6\% = \frac{6}{100} = \frac{3}{50}$;
$30\% = \frac{30}{100} = \frac{3}{10}$;
$1.2\% = \frac{1.2}{100} = \frac{3}{250}$;
$12.5\% = \frac{12.5}{100} = \frac{1}{8}$;
$175\% = \frac{175}{100} = \frac{7}{4}$;
$20\% = \frac{20}{100} = \frac{1}{5}$;
$16\% = \frac{16}{100} = \frac{4}{25}$;
$205\% = \frac{205}{100} = \frac{41}{20}$;
$9\% = \frac{9}{100}$;
$4\% = \frac{4}{100} = \frac{1}{25}$;
$37.5\% = \frac{37.5}{100} = \frac{3}{8}$;
$3.2\% = \frac{3.2}{100} = \frac{4}{125}$;
$15\% = \frac{15}{100} = \frac{3}{20}$;
$13\% = \frac{13}{100}$;
$40\% = \frac{40}{100} = \frac{2}{5}$;
$50\% = \frac{50}{100} = \frac{1}{2}$;
$70\% = \frac{70}{100} = \frac{7}{10}$;
$75\% = \frac{75}{100} = \frac{3}{4}$。
答案:
$10\% = \frac{10}{100} = \frac{1}{10}$;

$240\% = \frac{240}{100} = \frac{12}{5}$;
$5\% = \frac{5}{100} = \frac{1}{20}$;
$64\% = \frac{64}{100} = \frac{16}{25}$;
$6\% = \frac{6}{100} = \frac{3}{50}$;
$30\% = \frac{30}{100} = \frac{3}{10}$;
$1.2\% = \frac{1.2}{100} = \frac{3}{250}$;
$12.5\% = \frac{12.5}{100} = \frac{1}{8}$;
$175\% = \frac{175}{100} = \frac{7}{4}$;
$20\% = \frac{20}{100} = \frac{1}{5}$;
$16\% = \frac{16}{100} = \frac{4}{25}$;
$205\% = \frac{205}{100} = \frac{41}{20}$;
$9\% = \frac{9}{100}$;
$4\% = \frac{4}{100} = \frac{1}{25}$;
$37.5\% = \frac{37.5}{100} = \frac{3}{8}$;
$3.2\% = \frac{3.2}{100} = \frac{4}{125}$;
$15\% = \frac{15}{100} = \frac{3}{20}$;
$13\% = \frac{13}{100}$;
$40\% = \frac{40}{100} = \frac{2}{5}$;
$50\% = \frac{50}{100} = \frac{1}{2}$;
$70\% = \frac{70}{100} = \frac{7}{10}$;
$75\% = \frac{75}{100} = \frac{3}{4}$。
