Question

Ben walked 2/5 mile.Tonya walked 1/4 mile.What fraction of a mile did they walk in total?

Answer 1

First, find a common denominator (the bottom number) Then add the tops as usual. Four and five have a common denominator of 20 so: 8/20+5/20=13/20

Answer 2

First you need to make the denominators equivalent so you can add them.
$\frac{2}{5}$ × $\frac{4}{4}$=$\frac{8}{20}$

$\frac{1}{4}$ × $\frac{5}{5}$=$\frac{5}{20}$

Then you can add them together
$\frac{8}{20}$ + $\frac{5}{20}$
=$\frac{13}{20}$

They walked [tex] \frac{13}{20} [/tex] of a mile altogether
