harlan rides the bus $\frac{1}{4}$ mile and then walks $\frac{1}{8}$ mile to get home from school.\nsubtract to find how much farther harlan rides the bus than walks.\n$\frac{1}{4} - \frac{1}{8} = \frac{?}{?}$ mile
Answer
Explanation:
Step1: Find common denominator
Rewrite $\frac{1}{4}$ with denominator 8: $\frac{1}{4} = \frac{1\times2}{4\times2} = \frac{2}{8}$
Step2: Subtract the fractions
Subtract the numerators, keep denominator: $\frac{2}{8} - \frac{1}{8} = \frac{2-1}{8} = \frac{1}{8}$
Answer:
$\frac{1}{8}$ mile
