Question

One number is n and a second number is (⅔ n + 2). A third number is ⅙ n less than the second number. Express the sum of the three numbers in terms of n.

Answer 1

clearly, n + (⅔ n + 2) + (⅔ n + 2) - 1/6 n
so, what is 1+⅔+⅔-1/6 ? 2+2=?

Answer 2

n + 2n/3 + 2 + 2 n/3 + 2 - n/6
4 + n +8n/6 - n/6
4 + 6n/6 + 8n/6 - n/6
4 + 13 n/6
