Can anyone help me pls

1/2 if it's an answer if I'm wrong please fix my mistake.

Step-by-step explanation:

so this is how it should set up part/whole or certain item/total of items.

The item the equation ask us for a cap so you find how many times does the cap show on the spinner. In which I see 4. Then you look at the total of items on the spinner which is 8. which leaves it at 4/8.

However you need to simplify which only 4 can simplify the fraction 4/8÷4 which leaves the answer 1/2.

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates
