<human>:  Cary is 72 inches tall. Her younger brother Bill is half her height, and her younger sister Jan is 6 inches taller than Bill. How tall is Jan?
<bot>: How tall is Bill? ** First find Bill's height by dividing Cary's height by 2: 72 inches / 2 = <<72/2=36>>36 inches
How tall is Jan? ** Then add six inches to find Jan's height: 36 inches + 6 inches = <<36+6=42>>42 inches
