Carter is twice as tall as his 24” tall dog.  Betty is 12” shorter than Carter.  How tall is Betty in feet?
How tall is Carter? ** Carter is twice as tall as 24” dog so he is 2*24 = <<2*24=48>>48”
How tall is Betty? ** Betty is 12” shorter than Carter so Betty is 48-12 = <<48-12=36>>36” tall
How tall is Betty in feet? ** 12" is the same as 1 foot so Betty is 36/12 = 3 feet tall
