# What’s the Error? A student wrote an algebraic expression for “5 less than a number n divided by 3” as (n/3) - 5. What error did the student make?

**Solution:**

Given, a student wrote an __algebraic expression__ for “5 less than a number n divided by 3” as (n/3) - 5.

We have to find the error made by the student.

5 less than a number n = n - 5

5 less than a number n divided by 3 = (n - 5)/3

Correct __expression__ = (n - 5)/3

Expression written by student = (n/3) - 5

Therefore, the student divided the number ‘n’ by 3 instead of dividing (n-5) by 3.

**✦ Try This: **What’s the Error? A student wrote an algebraic expression for “6 less than a number n divided by 5” as (n/5) - 6. What error did the student make?

Given, a student wrote an algebraic expression for “6 less than a number n divided by 5” as (n/5) - 6.

We have to find the error made by the student.

6 less than a number n = n - 6

6 less than a number n divided by 5 = (n - 6)/5

Correct expression = (n - 6)/5

Expression written by student = (n/5) - 6

Therefore, the student made an error of quotient
