Question

In a recent survey, two-thirds of the 234 students in a freshman class said they watch television shows on their computer. Determine the correct arithmetic set up for determining how many students watch television on their computer

Answer 1

We know that 2/3 of all students watch TV shows on their computers.
And 234 students were in that survey.
2 / 3 * 234 = 156
Answer: 156 students watch shows on their computer.

Answer 2

Essentially, arithmetic set here means "number", so what we will be interested in is the answer to this question can be found here:

'two-thirds of the 234'.

that's all we need to know here. So let's count:
$\frac{2}{3} *234=2*78=156$

so the answer is simply 156!
