Question

Last week, Tracy walked her dog 2 2/5 miles. Maria walkedher dog 3 times as far. How many total miles did both girlswalk their dogs?

Answer 1

48/5 miles

Step-by-step explanation:

First, we need to convert the mixed number 2 2/5 into a fraction as follows:

`\begin{gathered} A(b)/(c)=((A* c)+b)/(c) \\ 2(2)/(5)=((2*5)+2)/(5)=(10+2)/(5)=(12)/(5) \end{gathered}`

Therefore, Tracy walked her dog 12/5 miles.

Then, Maria walked her dog 3 times as far, so Maria walked her dog:

`3*(12)/(5)=(3*12)/(5)=(36)/(5)`

So, Maria walked her dog 36/5 miles.

Now, both girls walk their dogs a total of:

`(12)/(5)+(36)/(5)=(12+36)/(5)=(48)/(5)`

So, the answer is 48/5 miles.
