Claim: The difference between two rational numbers always is a rational number
Proof: You have a/b - c/d with a,b,c,d being integers and b,d not equal to 0.
Then:
a/b - c/d ----> ad/bd - bc/bd -----> (ad - bc)/bd
Since ad, bc, and bd are integers since integers are closed under the operation of multiplication and ad-bc is an integer since integers are closed under the operation of subtraction, then (ad-bc)/bd is a rational number since it is in the form of 1 integer divided by another and the denominator is not eqaul to 0 since b and d were not equal to 0. Thus a/b - c/d is a rational number.
Answer:
The cost of 8 comic books is $14
Step-by-step explanation:
Given
Required
Determine the cost of 8 books
First, we need to determine the cost of 1 book
Divide through by 20
Then multiply both sides by 8 to get the cost of 8
Hence;
<em>The cost of 8 comic books is $14</em>
