Answer :
Answer:
D. N/7
Step-by-step explanation:
You want to know the math expression that represents the phrase, "the quotient of a number and seven."
Discussion
Every math operation has an English description of its result:
- sum — the result of adding two (or more) numbers in any order
- difference — the result of subtracting a second number from a first number. (Sometimes, the English usage means "the positive difference", which is the result of subtracting the smaller from the larger.)
- product — the result of multiplying two (or more) numbers in any order
- quotient — the result of dividing a first number by a second number
Application
You want the quotient of a number and seven. This is the result of dividing the number by 7.
When this is written as a math expression, we usually like to use a symbol to represent "a number." Your answer choices show that the symbol "N" is preferred for that purpose here.
The division ("divided by") symbol in math is either of ÷ or / (a fraction bar). So, "the quotient of a number and seven" means "N divided by 7". This can be written as ...
- N ÷ 7
- N/7
If the expression is typeset, it can be written as ...
[tex]\dfrac{N}{7}[/tex]

Additional comment
Here, the divisor (the denominator, or the number on the bottom) is a single number. If it were an expression, then it would need to be enclosed in parentheses in the plain-text forms:
- N ÷ (a +7)
- N/(a +7)
In the typeset form, the fraction bar serves the same grouping purpose that the parentheses serve.
[tex]\dfrac{N}{a+7}[/tex]
