Question

Your round-trip drive to work is 4 3/10 miles. how many miles do you drive to and from work in 3 days?

Answer 1

`12(9)/(10)` miles

Explanation:

In 1 day, you drive
`4(3)/(10)` miles [round trip, to and from]

So, in 3 days, you will drive
`4(3)/(10)*3` miles [to and from]

Changing
`4(3)/(10)` into improper fraction [for ease of multiplication] and multiplying by 3 gives us our answer:

`4(3)/(10)*3\\=(43)/(10)*3\\=(129)/(10)`

So, in total
`(129)/(10)=12(9)/(10)` miles are driven in 3 days
