Question

Barb walked 1.3 miles to her friend’s house and then 3/4 mile to the library. How far did Barb walk in all?

Answer 1

`2.05\ miles` or
`2(1)/(20)\ miles`

Explanation:

we know that

To calculate the total distance Barb walked, add the distance to her friend's house plus the distance to the library.

so

`1.3+(3)/(4)`

Remember that

`1.3=(13)/(10)`

substitute

`(13)/(10)+(3)/(4)=(13*2+5*3)/(20)`

`=(41)/(20)\ miles`

`=2.05\ miles`

Convert to mixed number

`(41)/(20)=(40)/(20)+(1)/(20)=2(1)/(20)\ miles`
