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

Hey there,
It take 45 min to complete 75% of the wall
1% = 45 / 75
      = 0.6
100 % = 0.6 x 100
           = 60 min
It takes her 60 mins or 1 hour to finish building the wall.

Hope this helps :))
