This afternoon Beth left school, rode the bus 1/5 of a mile, and then walked 1/10 of a mile to get home. How much far did Beth go in total?
Solution:
Find how much farther Beth rode the bus by subtracting [tex]\frac{1}{10}[/tex] from [tex]\frac{1}{5}[/tex].
You can use 10 as the common denominator.
Multiply the numerator and the denominator of [tex]\frac{1}{5}[/tex] by 2 to find an equivalent fraction.
[tex]\frac{1*2}{5*2} =\frac{2}{10}[/tex]
Now subtract the fractions. Subtract the numerators and keep the denominators the same.
[tex]\frac{1}{5} +\frac{1}{10} =\frac{2}{10}+\frac{1}{10}=\frac{3}{10}[/tex]
Beth rode the bus [tex]\frac{3}{10}[/tex] of a mile farther than she walked.
