Question

Dory is building a wall around her garden. It has taken 45 minutes and she is 75% done. What is the total time that will take her to finish building her wall?

Answer 1

So it's easier to calculate if you figure out how much time it took her to finish 25% of the wall. Since it took her 45 minutes to do 75%, it took her 15 minutes to do 25%. Then you just multiply.

Therefore, it takes her 60 minutes to finish building her wall.
