Let's express each of the given numbers in fraction, decimal, and percentage forms step by step.

### a. $$ \frac{2}{5} $$
1. **Fraction**: $$ \frac{2}{5} $$
2. **Decimal**: To convert the fraction to decimal, divide the numerator by the denominator:
   $$
   \frac{2}{5} = 0.4
   $$
3. **Percentage**: To convert the decimal to percentage, multiply by 100:
   $$
   0.4 \times 100 = 40\%
   $$

### b. $$ 1.50 $$
1. **Fraction**: To express $$ 1.50 $$ as a fraction, we can write it as:
   $$
   1.50 = \frac{150}{100} = \frac{3}{2} \quad \text{(simplified)}
   $$
2. **Decimal**: $$ 1.50 $$ is already in decimal form.
3. **Percentage**: To convert to percentage, multiply by 100:
   $$
   1.50 \times 100 = 150\%
   $$

### c. $$ 0.25 $$
1. **Fraction**: To express $$ 0.25 $$ as a fraction, we can write it as:
   $$
   0.25 = \frac{25}{100} = \frac{1}{4} \quad \text{(simplified)}
   $$
2. **Decimal**: $$ 0.25 $$ is already in decimal form.
3. **Percentage**: To convert to percentage, multiply by 100:
   $$
   0.25 \times 100 = 25\%
   $$

### d. $$ 30\% $$
1. **Fraction**: To express $$ 30\% $$ as a fraction, we can write it as:
   $$
   30\% = \frac{30}{100} = \frac{3}{10} \quad \text{(simplified)}
   $$
2. **Decimal**: To convert to decimal, divide by 100:
   $$
   30\% = 0.30
   $$
3. **Percentage**: $$ 30\% $$ is already in percentage form.

### Express $$ \frac{-5}{5} $$ as a percentage
1. First, simplify $$ \frac{-5}{5} $$:
   $$
   \frac{-5}{5} = -1
   $$
2. To convert to percentage, multiply by 100:
   $$
   -1 \times 100 = -100\%
   $$

### Summary of Results
- $$ \frac{2}{5} $$: Fraction: $$ \frac{2}{5} $$, Decimal: $$ 0.4 $$, Percentage: $$ 40\% $$
- $$ 1.50 $$: Fraction: $$ \frac{3}{2} $$, Decimal: $$ 1.50 $$, Percentage: $$ 150\% $$
- $$ 0.25 $$: Fraction: $$ \frac{1}{4} $$, Decimal: $$ 0.25 $$, Percentage: $$ 25\% $$
- $$ 30\% $$: Fraction: $$ \frac{3}{10} $$, Decimal: $$ 0.30 $$, Percentage: $$ 30\% $$
- $$ \frac{-5}{5} $$: Percentage: $$ -100\% $$
- $$ \frac{2}{5} $$: Fraction: $$ \frac{2}{5} $$, Decimal: $$ 0.4 $$, Percentage: $$ 40\% $$ - $$ 1.50 $$: Fraction: $$ \frac{3}{2} $$, Decimal: $$ 1.50 $$, Percentage: $$ 150\% $$ - $$ 0.25 $$: Fraction: $$ \frac{1}{4} $$, Decimal: $$ 0.25 $$, Percentage: $$ 25\% $$ - $$ 30\% $$: Fraction: $$ \frac{3}{10} $$, Decimal: $$ 0.30 $$, Percentage: $$ 30\% $$ - $$ \frac{-5}{5} $$: Percentage: $$ -100\% $$
