I would say 640.5 centimeters. However, remember that this is high school work, and I am only in middle school. This may not be correct, as I am doubting myself, yet cannot find errors in my work. Please take caution with this answer! Hope this isn't a detriment to you, bye! :)
Answer:
54.16%
Step-by-step explanation:
The percentage of books that are some is 54.16 %
In order to find that answer you would have to calculate the total number of small books (26) over the total number of all of the books (48).
The equation would be 26/48=0.5416 however Multiply that answer by 100 and you would get 54.16% and if you want to round to the nearest whole number it would just be 54%
