Marissa rode her bike to the park and back home. she lives 2 3/10 miles from the park. how many miles did marissa ride her bike in all?

So to answer this we would need to add 2 3/10 and 2 3/10 together to get the total amount of miles Marissa rode.
First add the numerators : 6/10 = 3/5
Then add the whole numbers : 2 + 2 = 4
The answer is 4 3/5 miles.
Hope I helped!
