A group of hikers walked 2 3/5 miles along a hiking trail. Another group of hikers walked 1/2 that distance with the first group before turning off onto another trail. How many miles did the two groups of hikers walk with each other?

Respuesta :

2 3/5 = 2  6/10
1/2 = 5/10
2 6/10 + 5/10 =
2 11/10 = 3 1/10
