Express each of the following as a fraction :
`0.25%`

Answer

To express `0.25%` as a fraction, follow these steps:

### Step 1: Convert the percentage to a decimal
To convert a percentage to a decimal, divide by 100.
So,
\[ 0.25\% = \frac{0.25}{100} \]

### Step 2: Remove the decimal point
To eliminate the decimal in the numerator, we can multiply both the numerator and the denominator by 100. This gives us:
\[ \frac{0.25 \times 100}{100 \times 100} = \frac{25}{10000} \]

### Step 3: Simplify the fraction
Next, we simplify the fraction \(\frac{25}{10000}\). We can divide both the numerator and the denominator by 25:
\[ \frac{25 \div 25}{10000 \div 25} = \frac{1}{400} \]

### Final Answer
Thus, \(0.25\%\) expressed as a fraction is:
\[ \frac{1}{400} \]
