GIVING BRAINLIEST! The diagram below shows the measurements of a bookcase. What is the total height of the bookcase?

Answer:
D. 18 1/8
Step-by-step explanation:
The three 1/3’s add up to 1. The 7 and 9 add up to 16. Add the 1 to that and you get 17. Then change the 1/2 to 4/8 and add that to the 5/8. You then get 1 and 1/8. Then you add that to the 17.
