The answer to your question is 0
What are you trying to find?
we know that
Quotient is the number resulting from the division of one quantity by another
Let
x--------> the first quantity
y------> the second quantity
q------> the quotient
So
-------> equation 1
in this problem
Substitute the values in the equation 1
Simplify
therefore
<u>the answer is</u>
The quotient is equal to 
Are there any parentheses in this equation? that would determine what you do first.
if it is (7+2)•4 your answer is 36.
if it is 7+2•4, then your answer would become 7+8, which is 15.
