Answer:
5 1/4
Step-by-step explanation:
* is multiplication
1 3/4 is 1.75
so
24/1.75 = 72/×
1.75 * 72 = 24 * x
126 = 24x
24x = 126
x = 5.25 or 5 1/4
 
        
             
        
        
        
1 week = 7 days 
10 weeks = 10×7 days 
 = 70 days 
if Ellen reads 1 book in a day 
Therefore, 
1 day = 1 book
70 days = 70×1
 = 70 books. 
Thus Ellen reads 70 books in 10 weeks. 
Hope helps
