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

Answer:

To drive to work takes $\frac{129}{20} miles$ and to drive from work takes $\frac{129}{20} miles$  in 3 days.

Step-by-step explanation:

The round trip to work take $4\frac{3}{10} = \frac{43}{10}$ miles. So for 3 days, the round trip will take:

$\frac{43}{10} .3$

$\frac{129}{10} miles$

and for to and from work, it will be:

$\frac{\frac{129}{10}}{2}=\frac{129}{20}$

Hence, to drive to work takes $\frac{129}{20} miles$ and to drive from work takes $\frac{129}{20} miles$  in 3 days
