Hello!
The formula for volume of a rectangular prism is: 
V = lwh
Let's convert the dimensions to decimals, and then use the formula to solve. 
8 1/2 = 8.5 as a decimal.
7 = 7 as a decimal. 
2 1/2 = 2.5 as a decimal. 
Multiply: 
V = 8.5 × 7 × 2.5 
V = 59.5 × 2.5 
V = 148.75
148.75 = 148 3/4 as a fraction because if you convert 3/4 to a decimal by dividing the numerator by the denominator, it equals 0.75. 
ANSWER: 
The volume of the book is 148 3/4 inches cubed.

Answer: 1/6
Step-by-step explanation:
1/2 divided by 3/1 turns into 1/2 x 1/3 and when multiplying numerators and denominators with each other, you get 1/6.
 
        
                    
             
        
        
        
$3.29*0.65(because you're paying 65% of the original price)
$2.14(this answer is rounded up to 2.14. if you don't round, it is 2.13)
