Work Step by Step

To convert the fraction $\frac{1}{4}$ to decimal form, first rewrite it as an equivalent fraction that has a denominator of 100. $\frac{1}{4}=\frac{x}{100}\rightarrow$ cross multiply $1\times100=4x\rightarrow$ divide both sides by 4 $100\div4=4x\div4\rightarrow$ simplify $25=x$ The equivalent fraction is $\frac{25}{100}$. Since the denominator has 2 zeros, move the decimal 2 places to the left in the numerator to express as a decimal. $\frac{1}{4}=\frac{25}{100}=0.25$, so $25\frac{1}{4}=25.25$
