boris is on his way home in his car. he has driven 15 miles so far which is three fifths of the way home. what is the total length of his drive?

Answer 1

15 miles = 3/5 of the trip

Imagine 5 empty blocks, each one representing 1/5 of the trip

If 3 empty blocks (3/5) = 15, then 1 empty block = 5

The whole trip can be represented by:

1/5 + 1/5 + 1/5 + 1/5 + 1/5 or

5 + 5 + 5 + 5 + 5

25 miles
