Expressions

Let k represent an unknown number, express the following expressions:

1. The sum of the number n and two
2. The quotient of the number n and nine
3. Twice the number n
4. The difference between nine and the number n
5. Nine less than the number n

Result

k1 = (Correct answer is: n+2) Wrong answer
k2 = (Correct answer is: n/9) Wrong answer
k3 = (Correct answer is: 2n) Wrong answer
k4 = (Correct answer is: 9-n) Wrong answer
k5 = (Correct answer is: n-9) Wrong answer

Solution:

k1=n+2
k2=n/9
