Decide if each expression represents one third the sum of 5 and 4.

Question

Choose one of the options below.

1. 1/3x(5+4)
2. 1/3x5+4
3. (1/3x5)+(1/3x4)
4. 1/3+(5x1/3)+4

Answer 1

The sum of 5 and 4 would be represented by the expression (5+4).

One third of that would be equivalent to multiplying by 1/3.

Thus, the answer is the first option: 1/3x(5+4).
