Beth built a tower of blocks that is 29 1/2 inches tall. Ken built a tower that is 30 1/8 inches tall, and Tara built a tower that is 59 3/4 inches tall. Beth thinks if she and Ken combine their towers it will be the same height as Tara's tower. Do you agree? Show or explain how you know.
I disagree with Beth.
If I add Beth and Ken's tower together it will be 59 5/8 inches tall and Tara's tower is 59 3/4 inches tall. If you change 59 3/4 to eights you get 59 6/8 which is a little more than 59 5/8.
