Work Step by Step

Convert $4.25$ into a fraction 1. Split up $4.25$ into $4$ and $0.25$ $$4=\frac{4}{1}$$ $$0.25=\frac{1}{4}$$ 2. Multiply $\frac{4}{1}$ by $\frac{4}{4}$ to get a common denominator between $\frac{4}{1}$ and $\frac{1}{4}$ $$\frac{4}{1}\times\frac{4}{4}=\frac{16}{4}$$ 3. Add $\frac{16}{4}$ and $\frac{1}{4}$ $$\frac{16}{4}+\frac{1}{4}=\frac{17}{4}$$
