Sum means the result of addition.
Quotient means the result of division.
Product means the result of multiplication.
The product of 3 and 7 is 21, because:
3 × 7 = 21
Therefore, the quotient is 21.
Let the sum of the facing page numbers = x:
Therefore, x/5 = 21
Rearranging the equation to find x (the sum of the facing page numbers) gives us:
x = 21 × 5
= 105
So the sum of the facing page numbers is 105.
The only two adjacent numbers which add up to 105 are 52 and 53, so the facing page numbers must be 52 and 53.

Answer:
Marisa has made 6 sandwiches.
Step-by-step explanation:
The pounds of roast beef required to make each sandwiches is
, and not
as erroneously typed in the question.
Given that each deli sandwiches made, uses
pounds of roast beef.

pounds left.
Thus,
pounds of roast beef used = 5 - 2
= 5 - 
= 
= 
= 2
Marisa had used 2
pounds of roast beef. So that;
the number of del sandwiches made = 2
÷ 
=
÷ 
= 6
Therefore, the number of sandwiches made by Marisa is 6.
