Explanation:

Step1: Recall the concept of percent

Percent means "out of 100". A whole is 100%.

Step2: Calculate half as a percent

Half is $\frac{1}{2}$, and $\frac{1}{2}\times100 = 50\%$.

Step3: Calculate part of ten - part division as a percent

If a total is divided into ten parts, each part is $\frac{1}{10}$, and $\frac{1}{10}\times100=10\%$. A dime is $\frac{10}{100}$ of a dollar, so it is 10%.

Step4: Calculate part of four - part division as a percent

If a total is divided into four parts, each part is $\frac{1}{4}$, and $\frac{1}{4}\times100 = 25\%$. A quarter is $\frac{25}{100}$ of a dollar, so it is 25%.

Answer:

100; 50; 10; 10; 25; 25
