What is the expression? the sum of a number and 5, all divided by 6

(n+5)/6

n is a number plus 5. All divided by 6

(x+5)/6

Step-by-step explanation:

Let's assume the number is x. The sum of a number means addition so when you see "the sum of", it means addition. The things that are getting added are x and 5 so it becomes x+5. Then you divide x+5 by 6 and you get (x+5)/6

I added parentheses because I didn't know how to show the full fraction.

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.
