# The height of a TV antenna is 11ft 7in. If the height of a building is 64ft 9in, find the total height of a building including the antenna.

I kept trying to do this, but I never learned this so I have no idea how to do this.

adding them, I get

75 ft 16 inches or

76 feet 4 inches.

It is time to learn this. Add the feet, add the inches. If inches is over 12, convert that to feet.

So all you have to do is add?
