A. 1/3 x (8+9)

Step-by-step explanation:

When you multiply something by a fraction, you are figuring out what fraction it is of the whole. And in the diagram, it is asking for you to give the equation to figure out what 1/3 of 8+9 is, and you also have to make sure that the parentheses are there because you want to multiply 1/3 by the sum of 8+9, not by 8 and then add 9.
