conversations.value: Kevin has a tree growing in his garden that is currently 180 inches tall. That is 50% taller than it was when he planted it there. How tall was the tree, in feet, then?

conversations.value: Since it is 50% taller, then 180 inches is 100% + 50% = 150% of its height then.
  So each 1% is equal to 180/150 = 1.2 inches.
  So, its height then was 1.2 x 100% = 120 inches.
  Since 1 foot is equal to 12 inches, then 120 inches is equal to 120/12 = 10 feet.
