TASK
The day there were not buses due to the transportation strike, you decided to go on foot. When you have walked 5/8 of the distance from your house to the school, you stopped to drink a soda. At that moment, how many kilometers were you from the school?

Post your comment explaining how you got the answer.

Hints:
1) Does the problem give you all the data you need to solve it?
2) How can you find all the data?
3) Will a drawing help you figure out a way to solve the problem?
4) What operations do you need to solve the problem?

See you around!
