$\frac{15}{60}=$25%
$\frac{13}{20}=$65%
$\frac{16}{25}=$64%
$\frac{60}{200}=$30%
$\frac{48}{50}=$96%

答案： 解析：本题考查分数与百分数的转化。分数转化为百分数，先将分数化成小数（除不尽的保留三位小数），再把小数化成百分数，即把小数点向右移动两位，同时在后面添上百分号。
答案：$21\%$；$34\%$；$60\%$；$9\%$；$35\%$；$34\%$；$75\%$；$60\%$；$12.5\%$；$55\%$；$8\%$；$28\%$；$30\%$；$62.5\%$；$25\%$；$70\%$；$25\%$；$65\%$；$64\%$；$30\%$；$96\%$。
