Answer to Problem 42HP

Ramon is correct

Explanation of Solution

Given:

"Five less than a number"

    John
    Let n represent the number
    5−n    		Ramon
    Let n represent the number
    n−5

Calculation:

To verify who has written the expression correctly, consider the phrase

"Five less than a number"

So let 'n' represent the number

Now, the word "less than" indicates subtracted from.

That is, it means 5 subtracted from the number which is n.

Thus, the correct expression is

  n−5

Hence Ramon is correct.

Conclusion:

Hence Ramon is correct.
