Answer: Jane's height is 59 9/20 inches.
Explanation:
We are given that Tim is 56 3/4 inches tall.
Joey is 1 1/2 inches taller than Tim, so Joey's height is:
56 3/4 + 1 1/2 = 58 1/4 inches
Jane is 1 1/5 inches taller than Joey, so Jane's height is:
58 1/4 + 1 1/5 = 59 9/20 inches
Therefore, Jane's height is 59 9/20 inches.
