It is 3/5 mile from Elaine's home to her school. It is 1/10 mile from her home to the library. How much farther is Elaine's home
Kipish [7]
3/5 is equivalent to 6/10

the school is 6/10 miles away
the library is 1/10 miles away

6/10-1/10=5/10

From her home to her school is 5/10 or 1/2 a mile farther than from her home to the library
