Question

Last Saturday, Flavia walked her dog 1 2/5 miles. Shazell walked her dog 5 times as far. How many miles total did both girls walk their dogs?

Answer 1

1 2/5 x 5

=7

7+1 2/5

=8 2/5 miles total

Answer 2

Answer:

$8\frac{2}{5}$ miles

Step-by-step explanation:

We have been given that Flavia walked her dog $1\frac{2}{5}$ miles. Shazell walked her dog 5 times as far.

The total distance walked by both dogs would be $1\frac{2}{5}$ miles plus 5 times $1\frac{2}{5}$ miles as:

$\text{Total distance walked by both dogs}=1\frac{2}{5}+5\times 1\frac{2}{5}$      

Convert mixed fractions into improper fractions:

$1\frac{2}{5}\Rightarrow \frac{1*5+2}{5}=\frac{5+2}{5}=\frac{7}{5}$

$\text{Total distance walked by both dogs}=\frac{7}{5}+5\times \frac{7}{5}$

$\text{Total distance walked by both dogs}=\frac{7}{5}+\frac{35}{5}$  

$\text{Total distance walked by both dogs}=\frac{7+35}{5}$  

$\text{Total distance walked by both dogs}=\frac{42}{5}$  

$\text{Total distance walked by both dogs}=8\frac{2}{5}$  

Therefore, both girls walked $8\frac{2}{5}$ miles their dogs.
