the circle graph at the right shows eye colors of the students in Mr.Chare's 4th hour class. If 7 students have either green or hazel eyes, how many students are there in the class?

Circle graph is..
12% gray
24%hazel
4% green
36% brown
24% blue

I need help solving this, thank you so much.

28 percent have either green or hazel

Numberstudents*.28=7
solve for numberstudents.

To solve this problem, we need to find the total number of students in Mr. Chare's 4th hour class.

First, let's calculate the combined percentage of students with green or hazel eyes. According to the given graph, the proportion for green eyes is 4% and for hazel eyes is 24%.

The sum of these percentages is 4% + 24% = 28%. This means that 28% of the students have either green or hazel eyes.

We now have the equation:
Number of students * 28% = 7

To solve for the number of students, divide both sides of the equation by 28%:
Number of students = 7 / 0.28

Dividing 7 by 0.28 gives us the answer:
Number of students = 25

Therefore, there are 25 students in Mr. Chare's 4th hour class.

There are 30 stundent in the class.Four fifths of them have brown eyes.How many student have brown eyes
