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

you take 4x3 = 12 and than add in the 3/10x3 which is 9/10 so you can write this as 12.9 or 12 and 9/10

Answer 2

To drive to work takes
`(129)/(20) miles` and to drive from work takes
`(129)/(20) miles` in 3 days.

Explanation:

The round trip to work take
`4(3)/(10) = (43)/(10)` miles. So for 3 days, the round trip will take:

`(43)/(10) .3`

`(129)/(10) miles`

and for to and from work, it will be:

`((129)/(10))/(2)=(129)/(20)`

Hence, to drive to work takes
`(129)/(20) miles` and to drive from work takes
`(129)/(20) miles` in 3 days
