The correct answer is: $0.25$
Explanation
One fourth means the fraction $\frac{1}{4}$. To convert a fraction to a decimal you can divide the numerator by the denominator or convert to hundredths.
Steps:
- First step: $$\frac{1}{4}$$
- Second step (division): $$1 \div 4 = 0.25$$
- Final step (as hundredths): $$\frac{1}{4} = \frac{25}{100} = 0.25$$
Therefore, one fourth as a decimal is $0.25$.
